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.
