cmd/compile: un-hide closure func if parent expr moved to staticinit

If the function referenced by a closure expression is incorporated
into a static init, be sure to mark it as non-hidden, since otherwise
it will be live but no longer reachable from the init func, hence it
will be skipped during escape analysis, which can lead to
miscompilations.

Fixes #59680.
