[FIR] Properly assign <local> packages to symbols

This prevents `FirConflictsExpressionChecker.kt`
from missing conflicting local functions. It used
to due to inconsistencies in assigning `<local>`,
and this commit makes it a bit more
straightforward.

The change in KtClassTypeQualifierRenderer
prevents `FirOverrideImplementTest.testLocalClass`
from failing in `intellij`. It didn't fail for
callables, because `KtCallableSignatureRenderer`
doesn't try to render packages.
