basic: Move various macros from assert-util.h to assert-fundamental.h

ASSERT_PTR() and friends in assert-fundamental.h make use of assert()
and assert_se() which when not building for sd-boot are defined in
assert-util.h. Because assert() from glibc is only overridden in
assert-util.h, the macros in assert-fundamental.h still end up using
the glibc assert.

Let's fix this by moving the required macros and related logic to
assert-fundamental.h.
