[Analysis API FIR] KtSymbolContainingDeclarationProvider: support script declarations

This commit also fixes a missing symbol for KtScriptInitializer
and some symbol pointers
Many tests marked as 'DO_NOT_CHECK_NON_PSI_SYMBOL_RESTORE'
due to KtFirFileSymbol#createPointer logic – the pointer can
be created only for PSI
