7f2b8cd8fc tint: Refactor Extensions / Enables.
* Extract ast::Enable::ExtensionKind to ast::Extension.
* Move the parsing out of ast::Enable and next to ast/extension.h
* Change the ast::Enable constructor to take the Extension, instead of
  a std::string. It's the WGSL parser's responsibility to parse, not the
  AST nodes.
* Add ProgramBuilder::Enable() helper.
* Keep ast::Module simple - keep track of the declared AST Enable nodes,
  don't do any deduplicating of the enabled extensions.
* Add the de-duplicated ast::Extensions to the sem::Module.
* Remove the kInternalExtensionForTesting enum value - we have kF16
  now, which can be used instead for testing.
* Rename kNoExtension to kNone.

62bfd318ae tint: Implement f16 keyword in Tint frontend
This patch:
1. Add the `f16` WGSL extension.
2. Add `f16` as keyword, and remove it from reserved word list.
3. Add ast::f16 and sem::f16, and implement validation that using `f16`
   type must be with `f16` extension enabled.
4. Add `Number<NumberKindF16>` for f16 literal and constant, and add
   `ast::FloatLiteralExpression::Suffix::kH`.
5. Add placeholder in all writer which report error when try to emit f16
   type.

8822e2966a tint: Merge [S|U]intLiteralExpression
Merge SintLiteralExpression and UintLiteralExpression with
IntLiteralExpression. IntLiteralExpression has a new Suffix field which
indicates whether the literal is either a:
• 'i' suffixed integer literal
• 'u' suffixed integer literal
• no-suffix integer literal

Have the SPIR-V reader produce no-suffixed literals for i32 types, to
keep this change small. In future changes the SPIR-V reader will
produce 'i' suffixed types for these.

Have all consumers of IntLiteralExpression treat unsuffixed integers the
same as 'i'-suffixed literals. Unsuffixed will be treated as abstract in
future changes.

Removed SemHelper::TypeOf(const ast::LiteralExpression* lit).

26ebe5ec36 tint: Refactor if-else statement representation
Instead of using an `if` node that has a list of `else` statements,
make each `if` statement have a single optional `else` statement,
which may itself be an `if` statement (or just a block statement).

This better matches the WGSL grammar (now that we have removed
`elseif`), and simplifies various pieces of code that handle these
statements.

7098d3d692 tint: Add enable directive for extensions
In this CL the enable directive is implemented.
1. Add AST node for enable directive, assign a ExtensionKind (enum) for
each supported extension.
2. Use an unorder_set in ast::Module to record all required extensions'
kind.
3. Provide inspector methods for getting names of used extension, and
getting all used enable directives' extension names and location.
4. For different writer, the extension nodes are handled in different
ways. MSL and HLSL writers will just ignore the extension nodes, while
SPIRV and GLSL writers will emit corresponding code.
5. Implement unittests and end2end test for enable directive and
inspector, using a reserved extension name `InternalExtensionForTesting`.

dfc1a2c081 Remove support for the @stride attribute
We still use the StrideAttribute AST node in the SPIR-V reader for
strided arrays and matrices, which are then removed by transforms.

The WGSL parser no longer has to handle attributes on types.

8bcecf365d Remove @block attribute
Since this was the only attribute allowed on structures, we can also
remove the parsing code for them. However, we still need to have
attributes on the struct AST node, since the AddSpirvBlockAttribute
transform adds one.

453d5ae84e Terminate line comments with \v, \f, and \r
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.

64b775419d Error on invalid UTF-8 sequences
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.

b86895da5f Fix assert in MSVC debug builds when parsing unicode
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.

Tint makes heavy use of RTTI via virtual methods. Give the compiler the
opportunity to optimize away some of these virtuals.
