Vyacheslav Levytskyy b512df660e [SPIR-V] Improve Tablegen instruction selection and account for a pointer size of the target (#88725) ...

This PR resolves the issue that SPIR-V Backend uses the notion of a
pointer size of the target, most notably, in legalizer code, but
Tablegen instruction selection in SPIR-V Backend doesn't account for a
pointer size of the target. See
https://github.com/llvm/llvm-project/issues/88723 for a detailed
description. There are 3 test cases attached to the PR that reproduced
the issue, when dealing with spirv32-spirv64 differences, and are
working correctly now with this PR.
