Summary: Investigate migrating `gn` logic to the `mozbuild` build system proper → Migrate `gn` logic to the `mozbuild` build system proper
Depends on: 1654112

The plan is to augment the existing ad-hoc gn support with in-build support, so that while we're building the RecursiveMake backend we'll run gn to dynamically compute the compile arguments/etc., and then apply those immediately without requiring the current manual one-time work of running GnConfigGen and GnMozbuildWriter on a bunch of OS'es and checking those in as a mega-patch.

We're blocked on doing that now because gn gen requires Python 2, and requiring Python 2 to build Firefox again would be a huge regression. The next version seems to have better Python 3 support so we'll postpone this work until the current update is done.
