Bump to v8 145 (#4073)

# Description of Changes

This release has a couple of patches I've been waiting on for a bit:

* denoland/rusty_v8#1868, which mean we no
longer have to use high slot indexes.
* denoland/rusty_v8#1886, which allows us to
lazily parse sourcemaps.
* I also bumped `sourcemap` to get
getsentry/rust-sourcemap#137, so that we no
longer have to have our hack to work around that.
* denoland/rusty_v8#1892, which allows us to
re-enable `run_timeout_and_cb_every` (though I haven't done that in this
PR)

# Expected complexity level and risk

2: v8 is a very big and important dependency, but also very stable.

# Testing

- [x] No change to behavior; automated testing is sufficient.
