cmd/compile/internal/types2: revert to three-phase alias resolution

This change reenables the legacy three-phase resolution
(non-alias typenames, aliases, the rest) even when
GODEBUG=gotypesalias=1. Unfortunately the existing test case
for #50259 causes the simpler logic to fail.

Updates #50259
Updates #65294
