Add a make pr target for an easy "do automated checks for PR" command

[Groxx]

We already have a fair number of quicker and more focused commands, but they can be hard to remember to run / remember when to run.
So now we have one command that should do everything that's reasonably quick: make pr
(it still takes a couple minutes)

I've avoided adding tests to this because tests take quite a lot longer and aren't totally isolated / setup-free,
and tbh I tend to just push tests to CI because it's more comprehensive anyway.
Arguably (quick, stable) unit tests should be included though, and if we can figure out a safe set to run it'd be easy to add.

This same command will also be added to the client repo, as it has similar needs, and if/when we add submodules
there we'll need a make tidy and possibly other things too. Better to standardize on something simple.
