[mlir] Add support for querying the ModRef behavior from the AliasAnalysis class

This allows for checking if a given operation may modify/reference/or both a given value. Right now this API is limited to Value based memory locations, but we should expand this to include attribute based values at some point. This is left for future work because the rest of the AliasAnalysis API also has this restriction.
