[IR2Vec] Make IR2VecCategory externally visible and reuse in llvm-ir2vec cl options

[svkeerthy]

Consolidate IR2Vec option categories to use a single shared category across the library and tool.

With this change the cl options defined in IR2Vec.cpp are visible in llvm-ir2vec tool. This is necessary as we use the same options in the tool.
