ci: move CMake into base packages

This is already used in multiple CIs, and will soon become a requirement
for most CIs, i.e when we migrate depends packages to use CMake, for
example:
https://github.com/bitcoin/bitcoin/pull/21778#issuecomment-1885576324.

Some of the CIs in 21778 are failing because CMake isn't available, so
just break this out and make CMake globally available.
