Description

This is the tracking issue for -Zpanic-abort-tests and related functionality.

Specifically, this flag switches the default test strategy of (loosely) a thread per test to a process per test, and implements the associated functionality of collecting process failures and treating that as passing/failing the test. It also includes a currently unstable option in test binaries, --force-run-in-process.

This was originally added in #64158 and Cargo support landed in rust-lang/cargo#7460.
