This patchset contains everything needed to integrate KASAN and KUnit.

KUnit will be able to:
(1) Fail tests when an unexpected KASAN error occurs
(2) Pass tests when an expected KASAN error occurs

Convert KASAN tests to KUnit with the exception of copy_user_test
because KUnit is unable to test those.

Add documentation on how to run the KASAN tests with KUnit and what to
expect when running these tests.

Depends on "[PATCH v3 kunit-next 0/2] kunit: extend kunit resources
API" patchset [1]

[1] https://lore.kernel.org/linux-kselftest/1585313122-26441-1-git-send-email-alan.maguire@oracle.com/T/#t

Changes from v3:
 - KUNIT_SET_KASAN_DATA and KUNIT_DO_EXPECT_KASAN_FAIL have been
 combined and included in KUNIT_DO_EXPECT_KASAN_FAIL() instead.
 - Reordered logic in kasan_update_kunit_status() in report.c to be
 easier to read.
 - Added comment to not use the name "kasan_data" for any kunit tests
 outside of KUNIT_EXPECT_KASAN_FAIL().
