feat(es/base): Make scope context same to the declared variable

[Austaras]

Description:
Mark scope with the same Mark as the declared variables inside them.

This PR may cause performance regression in non compress use cases, but the effect should be negligible.

BREAKING CHANGE:

And, as a side note, the whole Mark thing is not necessary for SWC. rustc uses Mark to mark which macro code come from, and in SWC Mark is used in two cases: variable shadowing as showed in this PR, and provide some additional information as in mark pure in compress. If the latter usage can be eliminated, we could use a single AtomicUSize to provide for all SyntaxContext.

swc-bump:

• swc_ecma_transforms_base

I'm unsure if it's fine to simplify' SyntaxContext' to single atomic usize at the moment.

No worry, even if it is, I currently don't have the capacity to apply such huge change.
