  -----------
  [DirectX] Implement DXILResourceBindingAnalysis (#137258)

`DXILResourceBindingAnalysis` analyses explicit resource bindings in the
module and puts together lists of used virtual register spaces and
available virtual register slot ranges for each binding type. It also
stores additional information found during the analysis such as whether
the module uses implicit bindings or if any of the bindings overlap.

This information will be used in `DXILResourceImplicitBindings` pass
(coming soon) to assign register slots to resources with implicit
bindings, and in a post-optimization validation pass that will raise
diagnostic about overlapping bindings.

Part 1/2 of #136786
