  -----------
  [HLSL][SPIR-V] Add `-fspv-enable-maximal-reconvergence` flag to clang dxc. (#163474)

Implement the frontend change to support maximal reconvergence feature.

The next work is to generate the corresponding SPIR-V instructions
(`OpExtension` and `OpExecutionMode`) based on the llvm ir added in this
CL `"enable-maximal-reconvergence"="true"`.
