async_hooks: improve resource stack performance

Removes some of the performance overhead that came with
`executionAsyncResource()` by using the JS resource array
only as a cache for the values provided by C++. The fact that we now
use an entry trampoline is used to pass the resource without
requiring extra C++/JS boundary crossings, and the direct accesses
to the JS resource array from C++ are removed in all fast paths.

This particularly improves performance when async hooks are not
being used.

This is a continuation of https://github.com/nodejs/node/pull/33575
and shares some of its code with it.
