Removes the validation logic that was blocking this copy from being
valid and update tests to ensure that it works properly.
Copy logic worked with this format as-is, so no updates were necessary.

The WGSL spec says that line comments are terminated by any blankspace
other than a space or a horizontal tab.
Also rename is_whitespace to is_blankspace and tighten up the
definition to only include the characters listed in the WGSL spec.

Invalid UTF-8 was being best-effort consumed, which given the right sequence of brokenness, could end up with diagnostic locations referring to bytes beyond the end of a line.
Improve the UTF-8 decoding so that it can detect when multi-byte codepoints are missing the high-bit being set.
Actually detect this in a lexer, and parser and produce errors.

This transform ensures that expressions are evaluated in the order
defined in the WGSL spec. It does this by making sure to hoist
expressions that have side-effects (calls) along with variables that may
receive these side-effects to lets in the correct order.

On MSVC debug builds (VS 2022), running Tint against the
"unicode\identifiers.wgsl" test was triggering the following assert:

std::isdigit, isxdigit, and isspace specify that the behaviour is
undefined if the argument's value is neither representable as unsigned
char nor equal to EOF. For example, see:
https://en.cppreference.com/w/cpp/string/byte/isdigit. As suggested on
cppreference, to safely use these functions, we should first convert the
char argument to unsigned char.

The timestampWrites in render/compute pass descriptor store the
timestamps at the beginning and end of passes, this requires validating
all timestampWrite members in BeginXxxPass and inserting the
timestampWrite cmd as close as possible to the BeginXxxPass and
EndXxxPass. To do that, we first record only the querySets and
queryIndexes that need to be used in BeginXxxPassCmd and EndXxxPassCmd,
then insert timestampWrite cmd after the native BeginXxxPass and before
the native EndXxxPass in backends.
This CL adds timestampWrites in render/compute pass descriptor
including the validation and tests first.
Implement timestampWrites in backends in following CL.

In GLSL, runtime-sized arrays are only valid in interface blocks, not
in structs. The existing code was attempting to avoid emitting structs
containing runtime-sized arrays but was confused by type aliases in
the AST resulting in arrays being missed.
The fix is to do the work on the semantic types instead, where type
aliases have been resolved.

Unlike other texture functions in GLSL, textureGather() and
textureGatherOffset() do not expect the refZ value to be appended to
the texture coordinates. It is passed as a regular argument. So append
refZ to coordinates by default, and pass as a regular parameter only
for the gather functions.

Multiple bugs here:
1) Like texture(), GLSL's textureLod() on depth textures returns a
scalar, and does not need to be swizzled. So set glsl_ret_width to
1 in that case.
2) Like texture(), GLSL's textureLod() always requires a Dref
parameter, so append a zero if not present.
3) GLSL's "lod" parameter to textureLod() is always a float, unlike
WGSL's textureSampleLevel() which is an i32 for depth textures,
so cast it.
Along the way, I discovered that textureLod() is not supported on
samplerCubeShadow or sampler2DArrayShadow (even on Desktop GL). So some
tests will never pass. Logged as https://crbug.com/dawn/1313
