  -----------
  [mlir][spirv] Add folding for SPIR-V Shifting ops (#74192)

Add missing constant propogation folder for LeftShiftLogical,
RightShift[Logical|Arithmetic].

Implement additional folding when Shift value is 0.

This helps for readability of lowered code into SPIR-V.

Part of work for #70704
