feat: Add ClangIR Protobuf Deserializer

No description provided.

Build is failing right now, but this is to be expected: CIROps.td within ClangIR was tweaked to enable default builders for every operation. This project's ClangIR needs to be updated to the one used for generating deserialization files (or, alternatively, the method of operator construction itself must be changed).

You can change the ClangIR version using on CI here.

Do you think the name change is necessary? It breaks the backward compatibility of the protocol.

As it's still work in progress, I assumed such changes would not create big issues. I introduced them to create uniform naming style for Enum values, so code generators can hold simpler logic. I can put the old names back, but it may complicate TableGen backends and its future maintenance.
