  Log Message:
  -----------
  [DirectX] Set whole-module flags prior to evaluating per-function flags (#139967)

Fixes #139024 and #139954

- Refactor DXILShaderFlags to compute the flags that apply to a whole
module before computing flags that apply individually to each function
- Make DXILResourceMap const, since it is not modified in
DXILShaderFlags
- Per-function shader flag analysis now initially starts with the set of
flags that apply to the whole module instead of starting from no flags.
This change fixes the above linked issues
- Fix shader flag tests affected by the above change
