fix: include constant kind in whereSymbol and findMatchingNodes queries (#487)

whereSymbolImpl used ALL_SYMBOL_KINDS (core 10, no constant) so
codegraph where could not find constants. findMatchingNodes defaulted
to FUNCTION_KINDS which also excluded constant. Switch whereSymbolImpl
to EVERY_SYMBOL_KIND and add constant to FUNCTION_KINDS default.
