-----------
[HLSL][RootSignature] Add basic parameter validations of Root Elements (#145795)
In this pr we go through and enforce the various bounded parameter
values for non-flag values and the valid flag combinations for
`RootDescriptor` and `DescriptorRange` flags.
For reference of the required checks, please see here:
https://github.com/llvm/wg-hlsl/blob/main/proposals/0002-root-signature-in-clang.md#validations-in-sema.
- Updates `SemaHLSL` to iterate through `RootElement`s and verify that
all non-flag parameters are within their bounds
- Updates `SemaHLSL` to iterate through `RootElement`s and verify that
all flag parameters are a valid combination
- Extends `RootSignature-err.hlsl` with testcases for all invalid
specifications
- Adds `RootSignature-flags-err.hlsl` with testcase for invalid flag
specifications
