resource, kunit: add test case for region_intersects()

add_memory_driver_managed()", v3.
The patchset fixes a bug of region_intersects() for systems with CXL
memory. The details of the bug can be found in [1/3]. To avoid similar
bugs in the future. A kunit test case for region_intersects() is added in
[3/3]. [2/3] is a preparation patch for [3/3].
This patch (of 3):
region_intersects() is important because it's used for /dev/mem permission
checking. To avoid possible bug of region_intersects() in the future, a
kunit test case for region_intersects() is added.
