[HLSL][RootSignature] Add lexing support for floating points (#137720)
- this takes care to add support to match the [behaviour of
DXC](https://github.com/microsoft/DirectXShaderCompiler/blob/34b6d0f91e6afd523bdc574836093f021713cce7/tools/clang/lib/Parse/HLSLRootSignature.cpp#L74)
acceptable floating point integers
Namely:
- Allow for specifying the decimal '.'
- Allow for specifying exponents with 'e' or 'E' and allow for 'f' to
denote an otherwise interpreted integer as a float
This pr is simply responsible of creating a token that could be
interpeted as a floating point integer by `NumericLiteralParser`. As
such, we are not required to validate that the special characters only
occur once and that 'f' is only at the end of the string. These will be
validated when invoking `NumericLiteralParser` during parsing.
Resolves #126565
