refactor(semantic): align handling of declaring symbol for function with TypeScript (#10086)

Browse Source 
The `Symbol` is based on the `TypeScript` implementation, but `TypeScript` doesn't support non-strict mode. So we tweaked the implementation to support non-strict mode before, but that held us back from adding symbol id for `declare function`, because `declare function oxc(): number; declare function oxc(): void` is valid, but we have no idea except introducing more symbol flags by to check whether it is a declare function. But introducing more symbol flags will lead to greater discrepancies between our implementation and `TypeScript`. https://github.com/oxc-project/oxc/pull/10074 has re-implemented the function redeclaration check in `checker` so that this PR can make a change to align with `TypeScript` implementation without leading to unexpected errors.

A lot of error messages are removed in snapshots, because they are all duplicated, which was introduced by https://github.com/oxc-project/oxc/pull/10074
