Apply a formatter for CMake files

[Gold856]

Formats all CMakeLists with gersemi.

[calcmogul]

Should we add gersemi to wpiformat? We already use black for Python formatting (pyformat.py), which has similar cmdline arguments.

[Gold856]

I think that's a good idea. I'll make a PR over there and change this one accordingly.

[calcmogul]

Should we generate a default .gersemirc file? What kinds of things does it let us configure? Are we OK with the default formatting @PeterJohnson?

[calcmogul]

wpiformat PR is wpilibsuite/styleguide#265.

[Gold856]

A .gersemirc file allows you to configure the same things the CLI allows you to configure. I'm going to add one because that allows us to change the settings without having to change it in wpiformat, which means we don't need to commit to wpiformat to make a formatting change, then commit to allwpilib to format it.

We should exclude cmake/toolchains--these files are mostly copied from OpenCV.
I personally think we should hold to 80, or 100 at most. 150 is way too long to be readable, particularly when it appears the tool combines lines that were previously manually split.

[calcmogul]

This should make it skip the cmake/toolchains folder:

Making this change will make wpiformat run on CMake files (you'll need to merge in main):

I don't know why, but wpiformat now wipes out all CMake files.

[PeterJohnson]

Tyler just merged wpilibsuite/styleguide#265, so that could be why?

[Gold856]

Well, yeah. I know it's my PR. What I'm trying to figure out is why it's wiping the files.

[calcmogul]

The task config in wpiformat 2023.35 was bad. Upgrade to 2023.36.
