[MLIR] Add a switch operation to the standard dialect
This is similar to the definition of llvm.switch, providing
unstructured branch-based control flow. It differs from the LLVM
operation in that it accepts any signless integer (not only an i32),
takes no branch weights (the same as the Branch and CondBranch ops),
and has a slightly different syntax for the default case that includes
it in the list of cases with an explicit `default` keyword.
Also included are several canonicalizers.
