  [WebAssembly] Rename wasm.catch.exn intrinsic back to wasm.catch

The plan was to use `wasm.catch.exn` intrinsic to catch exceptions and
add `wasm.catch.longjmp` intrinsic, that returns two values (setjmp
buffer and return value), later to catch longjmps. But because we
decided not to use multivalue support at the moment, we are going to use
one intrinsic that returns a single value for both exceptions and
longjmps. And even if it's not for that, I now think the naming of
`wasm.catch.exn` is a little weird, because the intrinsic can still take
a tag immediate, which means it can be used for anything, not only
exceptions, as long as that returns a single value.

This partially reverts D107405.
