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
