Cassie Jones 7f4b320ea8 [vim] Add initial syntax definition for .mir files
This initial definition handles the yaml container and the embedding of
the inner IRs. As a stopgap, this reuses the LLVM IR syntax highlighting
for the MIR function bodies--even though it's not technically correct,
it produces decent highlighting for a first pass.
