This gives template code a generic way to access IntLiteral/
getIVecComponent or FloatLiteral/getFVecComponent based on their
template type.
(Interestingly, we have BoolLiterals and support vectors of bools, but
don't have any paths in the optimizer that support constant-folding bool
vectors, so we don't have a getBVecComponent.)

We have the ability to copy or move an SkSTArray into an SkTArray, or
vice versa. However, this was not reflected anywhere in our test
coverage, and not all copy/move paths were exercised on every platform.
This led to a blind spot in our tests, meaning that Skia could
successfully build locally but fail on CQ bots due to SkSTArray usage in
various platform-specific code.

This makes numerous internal and GLSL types or intrinsics hidden from
public (runtime effect) SkSL. In particular:
- Only core numeric types are visible to all program types. GLSL types
involving images, textures, and sampling are restricted to internal use.
- sk_Caps is no longer visible to runtime effects.
- The set of intrinsics available to runtime effects is now a separate,
curated list in sksl_public.sksl. It exactly matches the GLSL ES 1.00
spec order.
- The blend intrinsics are no longer visible, which also fixes a bug.
These are nice, but we're not going to offer them yet - they involve
enums, which creates complications.

On an x86_64 Windows machine, the original GrAtlasTextOp is 1304 bytes
total, with the following breakdown:
- SkAutoSTMalloc<12, Geometry> = 1160 bytes, 16 of which are state and
the rest is all usable data for Geometry (each Geom is 96 bytes).
- Op state = 144 bytes, 8 of which is related to managing the
auto-malloc, 32 bytes hold the processor set, and 64 bytes come from
GrMeshDrawOp and parent classes.
- This was probably particularly unfortunate when we used the memory
pool for op allocations, because its block size was 16k. We would
quickly use up an entire allocation with <16 atlas text ops.
With this change and https://skia-review.googlesource.com/c/skia/+/331657,
GrAtlasTextOp is 264 bytes broken down as:
- GrTBlockList<Geometry, 1> = 152 bytes, 96 is an inline Geometry and
the rest is state.
- Op state = 112 bytes, 96 bytes hold the processor set and same
parent class state as before.
- The old atlas op had logic to grow its total storage following the
sequence 12, 18, 27, 40, 60, 90...
- The updated op configures the block list to grow with the following
sequence 6, 18, 36, 60, 90...
- This can be easily tweaked if we want to explore more aggressive or
conservative approaches. The current multiplier and policy was
chosen to reasonably match the old 12*(1.5)^n policy, which is not
an implemented option in GrBlockAllocator (although seems more
useful than the 2^n exponential policy).
Overall, a large reduction in the upfront allocation size, since it does
not assume every atlas text op will need to accumulate additional
geometry. GrTBlockList does have more overhead in what it tracks since
it has a linked list of byte arrays (24 vs. 56 bytes), but this lets it
avoid memory copies during a merge without it relying on realloc to be
successful. This extra built-in overhead is paid for by packing the
various flags/config options from 32 bytes into a 4 byte bitfield. Since
the atlas op does not upgrade its config as ops are merged, this
bitfield is effectively const and captures the majority of the logic
needed in combineIfPossible() with just an equals test.
GrTBlockList is one of the types I'm hoping can be relied upon by all of
Ganesh's ops to store the geometric/per-draw state that must be
accumulated during a merge. The atlas text op would be one of the early
adopters but also hopefully shows benefits on lower end devices. Perf
tests came out tied for me on my high-end machine, which is not
surprising, but I also feel like the code simplification is worth it
even if perf is no net change.
If it does turn out to have regressions, then we can revert and I can
circle back to optimizing the list class more.

optimize away comparisons of constant-vectors for floats, but fail to
do the same for ints.

The previous behavior leaked Skia-internal concepts into public SkSL.
Users coming from GLSL will expect that bindable/sampleable objects are
uniform (just like texture2D). This keeps the old support around (and
tested), but updates all of our examples to use 'uniform'.

This CL solves the fuzzer crash. Constant propagation of the negative
sign into the vector will be investigated in a followup CL.
This CL also adds a few cleanups into IRGenerator::constantFold.

One significant source of boilerplate in the SVG frontend is the
plumbing to ensure type safety all the way down from the XML layer to
the SkSVGNode layer. This is mostly an artifact of the top-down parsing
approach currently used by the SkDOM -> SkSVGDom building process.
One way to help remove some boilerplate is to perform attribute parsing
bottom-up, where each SVG node knows how to parse and populate its own
attribute values from a string-valued KV pair.
Additionally, bottom-up parsing allows us to support the case of the
same SVG attribute name having different meanings on different nodes
(e.g. the "type" attribute has different meaning on <feTurbulence>
versus <feColorMatrix>).
This CL adds some initial work to start us down that road, and ports the
attributes previously added for <feTurbulence> to use the new code path.

Tries to find and use newer API if available, with fallback to
older API as needed.
This also fixes family names for custom font collections.
