This is a draft because I want to test it in V8 first, but it's reviewable |

v8 side: https://chromium-review.googlesource.com/c/v8/v8/+/6946460 cc @linusg this may be annoying to migrate over, but should buy a teensy bit of performance |

Also there is a slight chance Diplomat's choice of type to represent usize isn't perfect. It ought to be fine, but so far Temporal hasn't had usizes over FFI and now it will. |

Split this out into a second PR for easier reviewability. boa-dev/temporal#572 makes TimeZone no longer need an allocation, which is a bit more invasive change than most. This was done in preparation for temporal_rs 0.1.0, and we expect far fewer C++ API breaking changes after that version.

This also moves a lot of internal stuff to taking TimeZone instead of &TimeZone. I think that's fine but I can revert if requested.
