  [HLSL] Implement DXILResourceBindingAnalysis

DXILResourceBindingAnalysis analyses all 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 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
