Also rename is_whitespace to is_blankspace and tighten up the

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.

On MSVC debug builds (VS 2022), running Tint against the
"unicode\identifiers.wgsl" test was triggering the following assert:
```
Program: C:\src\tint\out\build\x64-Debug\tint.exe
File: minkernel\crts\ucrt\src\appcrt\convert\isctype.cpp
Line: 36
Expression: c >= -1 && c <= 255
```
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.

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.

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
