[mlir][spirv] Update the spirv dialect scripts to accept the updated spirv json schema

[kuhar]

The SPIR-V dialect has scripts to define SPIR-V ops/enums/attributes based on the SPIR-V spec in the json format: https://github.com/llvm/llvm-project/tree/main/mlir/utils/spirv .

The json schema was recently updated: KhronosGroup/SPIRV-Headers#447. We should update the scripts to accept the new json format.

@kuhar posted #111778 to remove code that's not needed anymore since the grammar will have symbols de-duplicated.

As part of testing it out, ended up making also the following small fixes:

• [NFC][mlir][spirv] Fix syntax warnings in gen_spirv_dialect.py #111775
• [mlir][spirv] Ignore extra comma for category_args in gen_spirv_dialect.py #111776
• [mlir][spirv] Make gen_spirv_dialect.py more precise when finding inst_category #111777

Awesome @cmarcelo, thanks for taking care of this. I left some comments.
