The definitions of GENMASK() and GENMASK_ULL() do not depend any more
on __GENMASK() and __GENMASK_ULL(). Duplicate the existing unit tests
so that __GENMASK{,ULL}() are still covered.
Because __GENMASK() and __GENMASK_ULL() do use GENMASK_INPUT_CHECK(),
drop the TEST_GENMASK_FAILURES negative tests.
It would be good to have a small assembly test case for GENMASK*() in
case somebody decides to unify both in the future. However, I lack
expertise in assembly to do so. Instead add a FIXME message to
highlight the absence of the asm unit test.

Add some additional tests in lib/tests/test_bits.c to cover the
expected results of the fixed type BIT_U*() macros.

Add some additional tests in lib/tests/test_bits.c to cover the
expected/non-expected values of the fixed-type GENMASK_U*() macros.
Also check that the result value matches the expected type. Since
those are known at build time, use static_assert() instead of normal
kunit tests.

Following from the recent KUnit file naming discussion[1], move all
KUnit tests in lib/ into lib/tests/.
