chore: cleanup the dependencies on static_assertions and oxc_index. (#3095)

We used to export `static_assertions` as part of the `oxc_index`. It
would've made sense back when it was only a vessel for exporting other
crates - although even then it wouldn't make much sense other than being
convenient - Now with it turning into a port of `index_vec` and
potentially getting bigger as the result of specific needs of the
project; It makes much more sense to stop exporting it from `oxc_index`
and use the crate directly in places that used to use what `oxc_index`
were exporting.


PS: we may want to follow up this with an `oxc_asset` crate containing
our own set of assertion tools which would also export
`static_assertions`.
