Apply CMake formatting

[jwallwork23]

Today I discovered a CMake formatter: https://github.com/cheshirekow/cmake_format.

Seems like a good idea to add to the static analysis workflow. I did need to disable the formatter in a couple of places with particularly long lines.

(Most of the changes in this PR are auto-formatting changes.)

Nice @jwallwork23

Changes all look good to me.
As ever, needs a short comment/link adding to the documentation ;)

I'd also suggest putting cmakelang in the requirements.txt rather than pip installing it on its own.

My New Years resolution will be to write the docs with the code 👼

Good point.
