- Some completion performance tests (e.g. IntelliJ: "empty place typing
with library cache") spent a considerable amount of time in
`KtFirSymbolProviderByJavaPsi.getNamedClassSymbol`.
- This commit introduces `KtFirPsiJavaClassSymbol`, which implements
many `KtNamedClassOrObjectSymbol` properties with the `PsiClass`
instead of the FIR class. The `FirClassSymbol` is built only when
necessary. This improves performance when no "slow" properties need to
be computed for the symbol.
