Checks if there is a tricky GHC option in `ghc-options`. We will

one (in this case for `-fasm`) to make sure the field is scanned.

Note that this test is not atomic; comes with a "not a good relative

CI: GHC 9.2.1 -> 9.2.2

Fix Haddocks for `unAbiHash` and `mkAbiHash`

The existing Haddock documentation for `unAbiHash` and `mkAbiHash` appears to have been swapped, in error. This pull request swaps it back.

Document `cabal check` in the user guide

Bootstrapping update (including GHC 9.0, 9.2)

Keep it at only GHC 8.10.7 for macOS to save on CI time a bit.

- parametrize the bootstrap update Makefile target to make changing
  the list of GHC versions a bit easier
- add GHC 9.0.2 and 9.2.3 to the list of bootstrapping GHC versions
- regenerate the bootstrapping plans across all GHC versions

Apple Silicon Foreign Library Support (#8227)

- Allowed building Foreign Libraries for all architecture on apple
  silicon
- Updated error message to name Mac OS instead of OSX as supported
  platform
