Renames now that we have a build section

[henryiii]

I'd like to rename:

• cmake.targets -> build.targets
• cmake.verbose -> build.verbose

Old will work but be deprecated (minimum-version based).

[LecrisUT]

cmake.verbose would be useful to separate verbose for configure and build stage

[henryiii]

Probably also a configure section too, see #790. Either config or configure.

[henryiii]

I'm not sure what would go in config, though. cmake.args mirrors CMAKE_ARGS better, and we think of it as args to cmake more than configure-time arguments. configure.preset sounds good, though.

[LecrisUT]

Why not have cmake.args be alias to config.args? From CMake point of view it kinda mirrors the cmake without any option is implicitly configure. Would fit more naturally with build.args.

But also tool.scikit-build.config.xxx or tool.scikit-build.cmake.config.xxx? I don't think the latter is too verbose when it is being used within a group tool.scikit-build.cmake

[henryiii]

I don't like the idea of a permeant alias. Then you have to solve the question of what to do if both are specified. Though I do like the potential symmetry there somewhat, but these are cmake args as well, while build args are not cmake args.
