  [MLIR] Fix broken 'Successor<CPred<...>>' functionality in mlir-tblgen (#205375)

Previously, mlir-tblgen would generate incorrect C++ code when
passing a custom constraint to `Successor<...>`. The code would fail
to compile. We lacked end-to-end tests for this functionality and all
in-tree dialects only use `AnySuccessor` for their successors.

Custom C++ predicates for an Operation's successor(s) can be useful
in order to generate verification for certain conditions (e.g. that the
successor is the "next" block). This commit fixes the mlir-tblgen
functionality and adds end-to-end tests in the Test dialect for single
and variadic successors.
