Tests: Split part of include_directories test to a generic location.

The moved tests are related to paths in INTERFACE_INCLUDE_DIRECTORIES
in general, and when exporting, and covering cases of the install
location being within the build or source prefix etc.  Other build
properties containing paths should have similar tests, so this
allows some parameterization while keeping the preparation of the
various directory structures.
