We had special-case logic for copying array types from one symbol table

SPIR-V previously didn't know what to think when it encountered a Type
with a typeKind of kEnum, and would abort. These are now treated as
32-bit signed integers.
Metal previously emitted the SkSL enum typename, which is meaningless to
Metal since we do not emit the enum itself anywhere. Metal now emits
"int" for an enum-typed variable.
(GLSL already correctly emits "int" for enum types.)

This CL addresses the root cause of the fuzzer issue, by checking for
LayoutIsSupported before getting the MemoryLayout of a type. However,
this array ought to be detected as an error everywhere, as samplers are
opaque types; at present, this code compiles without error in GLSL and
Metal. This is an issue for followup CLs.
GLSL's actual support for arrays of samplers is interesting and probably
too nuanced for us to try to emulate:
https://www.khronos.org/opengl/wiki/Data_Type_(GLSL)#Opaque_arrays
"Under GLSL version 3.30, Sampler arrays (the only opaque type 3.30
provides) can be declared, but they can only be accessed by compile-time
integral Constant Expressions. So you cannot loop over an array of
samplers, no matter what the array initializer, offset and comparison
expressions are.
Under GLSL 4.00 and above, array indices leading to an opaque value can
be accessed by non-compile-time constants, but these index values must
be dynamically uniform. The value of those indices must be the same
value, in the same execution order, regardless of any non-uniform
parameter values, for all shader invocations in the invocation group."

Previously, GLSL and Metal code generators would emit a struct wherever
the type was first used in the code, regardless of where it was
originally defined or what scope the type needs to live in. This CL adds
a ProgramElement for struct definitions, so that structs will now appear
at the top-level as they were originally defined. In the case of Metal,
some special handling is also needed to handle the Globals struct
properly.
Not yet fully supported:
- No special handling for structs declared inside functions yet
- No support for structs in separate scopes with overlapping names
The severity of the remaining issues depends mostly on whether we want
to support structs inside functions in Runtime Effects.

Migrating chromium code to use SkImageFilters::Shader over
SkPaintImageFilter requires dithering to be preserved for its gradient
fills.
I debated always forcing it to true, but dithering was never turned on
for the turbulence filter and it's not necessary for const color shaders
Given that, I opted to just make it a parameter to the filter factory,
which seems okay since we're unlikely to embed dithering into SkShader
itself, it's a shading-related parameter of SkPaint, and if we migrate
to always dithering, then we can remove it.

This reverts commit 8636e13c2d.
Reason for revert: recording canvases with really big float bounds could
produce a non-empty integer rect bounds that became empty after mapping
it to (0,0,w,h) for the device. This meant resetForNextPictures logic of
updating QR bounds directly from the input bounds allowed state to become
inconsistent with computeDevClipBounds().
PS1->PS4 shows the 1-liner to just compute bounds from the device. This
means that, for now, we preserve the behavior of setting the QR bounds to
be actually empty. skbug.com/10997 is added to fix the underlying issue
with recorders and excessively large float bounds. If that change landed
first, I'd be able to reland this w/o any modifications, but have decided
that it's better to have all locations that modify fQuickRejectBounds use
the exact same expression.

GLSL does not allow most binary operations on bvec types; we can now
detect these and properly flag them as errors.
Note that `determine_binary_type` was also refactored. It originally
started with an enormous omni-switch over every possible Token type,
used to set various bools describing the type of binary expression at
hand. Instead of one big switch, this has been refactored into several
small switches in standalone functions that simply switch on the op and
immediately return true or false. Conceptually this seems like more
work (checking the op multiple times), but these tiny switches actually
boil down to little branchless shift-and-mask functions, so in practice
they should be quite efficient compared to the original omni-switch.

These checks are made very frequently; it significantly eases
readability to have dedicated accessor methods, versus the verbose
`x.typeKind() == Type::TypeKind::kFoobar`.

This is very unlikely to occur in real-world code, as it's somewhat
nonsense to use the comma operator in this way. However, it's better to
fail cleanly than to assert.

This new version always delivers the same results,
and I think can be simplified like this without
spoiling any of the bulk speed.
