refactor(semantic): populate declarations field in SymbolTable::create_symbol (#4461)

Browse source 
`declarations` field of `SymbolTable` is part of SoA group, where all `Vec`s in the group are indexed by `SymbolId`. Populate `declarations` field along with the rest in `create_symbol`, to prevent them getting out of sync. This will prevent bugs like the one fixed in #4460.
