refactor(ast): add SymbolId and ReferenceId

[Boshen]

This will make the linter easier to write when you need to get the binding for a given identifier reference.

This is already done for the HIR, I just need to combine the code for the AST.

I have met similar situation. I have to traverse the AST. With this requirement, to get the SymbolId of some identifiers, I need to get the atom of the Identifier, perform a query on ScopeTree to get SymbolId and thanks for I only care about the ids of root scope, so I don't need to search which scope the atom in.

@mysteryven You may start fixing all the issues we have accumulated 😅
