[SPIR-V] Add store legalization for ptrcast (#135369) 
This commits adds handling for spv.ptrcast result being used in a store
instruction, modifying the store to operate on the source type.

[SPIR-V] Fix OpVectorShuffle operands on load (#135954) 
The generated OpVectorShuffle was wrong, as the indices we pass are not
to select the vector to sample from, but the position in the vector.

[SPIR-V] Add pass to remove spv_ptrcast intrinsics (#128896) 
OpenCL is allowed to cast pointers, meaning they can resolve some type
mismatches this way. In logical SPIR-V, those are restricted. This new
pass legalizes such pointer cast when targeting logical SPIR-V.

For now, this pass supports 3 cases we witnessed:
 - loading a vec3 from a vec4*.
 - loading a scalar from a vec*.
 - loading the 1st element of an array.
