Vyacheslav Levytskyy 57f79371a5 [SPIR-V]: Add SPIR-V extension: SPV_KHR_cooperative_matrix (#96091) ...

This PR adds SPIR-V extension SPV_KHR_cooperative_matrix that "adds a
new set of types known as "cooperative matrix" types, where the storage
for and computations performed on the matrix are spread across a set of
invocations such as a subgroup" (see
https://github.com/KhronosGroup/SPIRV-Registry/blob/main/extensions/KHR/SPV_KHR_cooperative_matrix.asciidoc).

This PR also fixes https://github.com/llvm/llvm-project/issues/96170, a
new test cases is attached
(llvm/test/CodeGen/SPIRV/transcoding/OpPtrCastToGeneric.ll).
