  [WGSL] Should be able to parse hex and decimals when using 16-bit chars

Reviewed by Mike Wyrzykowski.

We use `std::from_chars` to parse hex and decimals numbers, which only works with
char*. Since the digits should be ascii in either case, and the maximum length is
is only 19, we just copy it into a char[20] buffer and continue using `std::from_chars`.

* Source/WebGPU/WGSL/Lexer.cpp:
(WGSL::Lexer<T>::lexNumber):
* Source/WebGPU/WGSL/tests/valid/constants-utf16.wgsl: Added.
