  [HLSL][RootSignature] Use "stringified" version for diagnostic output of punctuator tokens (#145827)

This pr will corrects the output with a stringified version of a
puncuator (eg `')'`) instead of its ascii value.

- Update `LexHLSLRootSignature` to fix the `DiagnosticBuilder`
`operator<<` overload to correclty format the puncuator
- Add testcase demonstrating the stringified version is output
