kunit: reduce stack usage in kunit_run_tests()

Some of the recent changes to the kunit framework caused the stack usage
for kunit_run_tests() to grow higher than most other kernel functions,
which triggers a warning when CONFIG_FRAME_WARN is set to a relatively
low value:

lib/kunit/test.c: In function 'kunit_run_tests':
lib/kunit/test.c:801:1: error: the frame size of 1312 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Split out the inner loop into a separate function to ensure that each
function remains under the limit, and pass the kunit_result_stats
structures by reference to avoid excessive copies.
