src: improve ToV8Value() functions

  • Cache the isolate value between calls
  • Introduce an overload for dealing with integers/numbers
  • Use the vectored v8::Array::New constructor + MaybeStackBuffer
    for faster array creation

src: simplify JS Array creation

Use ToV8Value() where appropriate to reduce duplication
and avoid extra Array::Set() calls.

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • commit message follows commit guidelines

Adding the backport-requested label, but ideally #25066 should be backported first.
