[compiler] Validate against component/hook factories (#34305)

Previously, the compiler would incorrectly attempt to compile nested
components/hooks defined inside non-React functions. This would lead to
scope reference errors at runtime because the compiler would optimize
the nested React function without understanding its closure over the
parent function's variables.

This PR adds detection when non-React functions declare components or
hooks, and reports a clear error before compilation. I put this under a
new compiler flag defaulting to false. I'll run a test on this
internally first, but I expect we should be able to just turn it on in
both compiler (so we stop miscompiling) and linter.

Closes #33978
