Feat: UnixCMakeExecutor

[crazywhalecc]

What does this PR do?

Replace all cmake builder to cmake executor. After refactoring we can control all cmake build process instead of updating every single file every time. This is one of prerequisites for #726 .

After this PR is merged, it will continue to:

• UnixAutoconfExecutor.
• New setDefaultEnv() for UnixShell to replace the redundant setEnv(['XXXFLAGS']), remove redundant execWithEnv().
• WindowsCMakeExecutor.

Could you also change execWithEnv to put the environment silently in prod mode and only print the executed command without environment flags? For debug mode I think we should print all environment flags we use, so pkg_config and pkg_config_path as well.

I plan to start resolving #726 conflicts after the next setEnv PR. This will make it clearer how we should modify the giant PR.

I've already done part of it, and it seems like basing the next PR on it will lead to even more confusion. Maybe breaking up parts of #726 into smaller PRs and merging them into the main branch first would be clearer.

Yeah that's fair.
