[CMake] Polish folders in generated Xcode project

[sgraenitz]

Summary

Group plugins by subfolder. Move liblldb-resource-headers to lldb misc. Avoid install-distribution related targets in IDE-enabled builds.

[sgraenitz]

Should give this folder structure in Xcode standalone builds:

We try to cut the parent folder names from the leaf folders, but that gets a mess quickly as not all names are consistent with their parent directories.

[sgraenitz]

I am going to land this, its cosmetics and the 9.0 branch was cut.
