  [WebAssembly] Refactor Wasm EH/SjLj error checking (#122466)

There were many overlaps between error checking and feature enabling
routines for Wasm EH and Wasm SjLj. This tries to factor out those
common routines in separate lambda functions.

This is not NFC because this ends up disallowing a few new combinations
(e.g. `-fwasm-exceptions` and `-emscripten-cxx-exceptions-allowed`), and
also deletes `-mllvm` from the error messages to share the same lambda
function between options with `-mllvm` and those without it.

This adds a few more tests but does not try to cover every single
possible disallowed combination.
