A glyph cache entry is made up of metrics, an image, and a path. If an
entry does not exist then nothing is known of the glyph yet. If there is
an entry it must have at least the metrics. The image and the path may
logically be added lazily as needed. Prior to this change it was not
possible to send both the image and the path of a single glyph. The
added test fails when a given strike is used for both the image and the
path. With this change the test passes, as the image is sent and the
path is sent, and both are merged into the remote glyph. The assertions
around not creating the glyph more than once are replaced with
assertions that no part of the glyph is set more than once.

The previous CLs have removed the last significant differences between
SkSL::String and std::string. This CL removes SkSL::String entirely and
replaces it with std::string throughout the code.
Apologies for the very long CL, but I have done my best to make it as
simple and reviewable as possible. The vast majority of changes are
simple replacement of `SkSL::String` with `std::string`. In the rare
spots where code is moved from one place to another, it is logically
unchanged.

By being on Recorder, more calls can directly access the ResourceProvider
without needing the Context or Gpu. A different ResourceProvider is
created for each Recorder. Each ResourceProvider stores a ref to the
GlobalCache so that it can access shared resources. Eventually each
ResourceProvider will also have its own ResourceCache for all non shared
Resources.
A big win of this change is that Context can be removed from Recorder.

Our SkVM code generator will always convert `pow(x, y)` into an
`approx_powf` call. However, in many cases, `x` or `y` might boil down
to an immediate value, and for some immediates, we can reduce the
operation into something much simpler:
- `pow(1, y)` is always 1
- `pow(2, y)` can be converted to `approx_pow2(y)`
- `pow(x, 0.5)` can be converted into `sqrt(x)`.
- `pow(x, 1)` can be converted to `x`
- `pow(x, 2)` can be converted to `x * x`
We could go further if there is a need, e.g. `pow(x, 4)` can become
`a = x * x; return a * a`, but these seemed like the best places to
start.

Also, it turns out that the inliner has ignored functions with out

account for this. So, did some additional cleanup:
- "InlinerHonorsGLSLOutParamSemantics" (the test in question) has been
moved to shared/ and renamed to "OutParamsAreDistinct."
- Removed test "OutParamsNoInline" as it is functionally the same as
"OutParams".

sk_SecondaryFragColor corresponds to an ES2-only concept
(gl_SecondaryFragColorEXT) and does not have any SPIR-V equivalent.
Two fixes were needed:
- sk_SecondaryFragColor shouldn't be in SPIR-V code at all. Report it as
an error when it appears.
- We don't stop compilation when this error is reported, so we need to
fix up the assertion that the fuzzer initially discovered.
Specifically, the fuzzer found that the `sk_SecondaryFragColor`
variable never got a SPIR-V ID assigned to it in fVariableMap, so the
compiler would assert when assembling an expression containing that
variable. Now, we make sure to populate fVariableMap with an (unused)
ID in `writeGlobalVar` to avoid this crash.

Upcoming dehydration / rehydration changes require $intLiteral and
$floatLiteral to be present in the symbol table (as all other private
types are). It turns out that even with them marked private, having
them in the symbol table allows them to be incorrectly accessed without
error due to a code path that fails to check for private types.
This CL takes care of that and ultimately results in better output from
PrivateTypes.

Move to RAII structs wrapping DrawWriter to control the append mode.
This allows each struct to define any extra template parameters/buffers
needed for the appended data, and expose only the appending API that
makes sense.
In follow up CLs, the RAII structs make it easy to support reserving
and returning vertex data, and add new appending modes.

GLSL ES2 behavior is explicitly undefined if an out-param is never
written to: "If a function does not write to an out parameter, the value
of the actual parameter is undefined when the function returns."
We do see divergence here in practice: SkVM's behavior (the parameter is
left alone) differs from my GPU's behavior (the parameter is zeroed
out).
SkSL will now report an error if an out parameter is never assigned-to.
There is no control flow analysis performed, so we will not report
cases where the out parameter is assigned-to on some paths but not
others. (Technically the return-on-all-paths logic could be adapted
for this, but it would be a fair amount of work.)
Structs are currently exempt from the rule because custom mesh
specifications require an `out` parameter for a Varyings struct, even if
your mesh program doesn't need Varyings.

This is mostly mechanical. The only interesting bit is that GrSLType was in include/private while SkSLType is in src/core so some #include patterns changed.

This is a precursor that makes supporting reserving/returning vertices
easier to implement, and adapt to it PatchWriter for the tessellating
path renderers.
It also has the small benefit of being slightly easier to follow, and
the buffer binding remains valid across pipeline changes.

Previously, when attempting to cast a huge value to an int, SkSL would
report an error, then return the IR for
`ScalarCast(Int, FloatLiteral(huge-value))` . Now, to minimize the blast
radius of the error, we report the error but return `IntLiteral(0)`.
We've already reported an error, so there's no need to preserve the
value, and zero is less likely to produce follow-up errors.
(A similar approach is used here and worked well: https://osscs.corp.google.com/skia/skia/+/main:src/sksl/ir/SkSLConstructorCompoundCast.cpp;l=57-59)

The test has been moved to shared/, since it's a valid test, but it is
no longer related to inlining, as the inliner no longer attempts to
inline functions with inouts at all.
Also, one function here (outParameterIgnore) actually invoked undefined
behavior and has been removed. According to the GLSL ES2 docs: "If a
function does not write to an out parameter, the value of the actual
parameter is undefined when the function returns." SkVM leaves the value
unchanged, so SKSL_TEST_CPU would pass, but a GPU might clear it (and in
fact, my GPU does).

with scalars. This works by splatting the scalar across every matrix
component and then performing the op componentwise. Our constant folder

Some paths through swizzle optimization would replace a swizzles with a
constructor--e.g. `float3(1, 2, 3).y` would be replaced with `float(2)`.
(Constructor::Convert was responsible for replacing this trivial
constructor with the literal `2.0`.)
The optimization code asserted that this replacement would succeed, but
the fuzzer managed to construct a counterexample where the constructor
rejected the value. Specifically, by nesting casts between int3 and
float3, it found a case where Constructor::Convert returned null because
the literal value was out of range for `int` types.
This assertion didn't really add value so removing it was harmless.
Constructor::Convert already reports an error when it fails, and null
returns are handled properly throughout.

The check in SkIsConvexPolygon that determines if a polygon winds around
multiple times turned out to not be correct in all cases. This has been
changed to a much simpler one -- if the sign of the edge vectors change
more than twice, then we know that we've wrapped around more than one
time.
In SkIsSimplePolygon, if both points adjacent to a vertex are on the
right side, we attempt to add both those edges to the active edge list.
However, if they are the same point, then we'll be adding the same edge
twice, which makes the strict ordering of the edge list invalid. Instead
we check for this case earlier on and reject the polygon.
