[mlir][llvm] Rename LLVMOpsInterfaces.td to LLVMInterfaces.td (NFC).

[gysit]

Summary

The revision renames LLVMOpsInterfaces.td since the the tablegen file
contains op and type interfaces.

[gysit]

This revision factors out the interface tablegen file rename discussed in https://reviews.llvm.org/D144851.

[Dinistro]

Thanks for splitting this into a separate revision. LGTM!
