Subject: [PATCH v2 3/3] kasan: delete CONFIG_KASAN_MODULE_TEST
Since we've migrated all tests to the KUnit framework,
we can delete CONFIG_KASAN_MODULE_TEST and mentioning of it in the
documentation as well.
I've used the online translator to modify the non-English documentation.

Each KUnit-compatible KASAN test prints one of multiple KASAN reports if an
error is detected. Then the test prints its number and status.
