LOG: [vim] Improve `iskeyword` for MLIR (#121750)

Define keywords for the MLIR syntax. This allows better recognition of
semantic constructs such as SSA value identification e.g. `%foo` which
gives improved motion handling when using 'word based' such as `w, e`.

This is based on the work done for the LLVM IR in
8c46413f343d0a5b8db48d958890b9038f03b70d.
