This also updates the bazel scripts to behave more like the C++ and Java
examples, and updates the copybara scripts to be able to sync up
`mostrobotpy`
I've been running my copybara syncs from this branch for a long time.
Finally deciding to PR it.
The biggest update was due to `mostrobotpy` absorbing the commands,
examples, and pyfrc libraries, but I also added in hooks to "enable" the
flakey `xfail` tests on the allwpilib side, and the ability to run
verbose or force push updates.
This is a high churn change whenever `mostrobotpy` switches from
pointing to `release-2027` to `development-2027`. The value isn't used
by the bazel build scripts, so there is no reason to have a zero impact
change on ~11 files muddying up the synchronization diffs.
In the `allwpilib -> mostrobotpy` direction, we update [this
](https://github.com/robotpy/mostrobotpy/blob/main/rdev.toml) config
file and run
[this](https://github.com/robotpy/mostrobotpy/blob/main/rdev.sh) script
which updates it in that repo during.
I manually did this change in #8503, but this will do it automatically
in the future
These are the scripts I've been using to sync between mostrobotpy and
here. I debated putting it in the "source of truth" that is
`mostrobotpy` , but I think it makes more sense here since it already
has bazel set up, and I've also recently added the ability to sync the
`commands-v2` repository, so having it all in one copybara script makes
sense.
This includes a helper python script to make it a little bit easier to
run.
