kasan: delete CONFIG_KASAN_MODULE_TEST

Browse Source 
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.

There are KASAN tests that allow verifying that KASAN works and can detect
certain types of memory corruptions. The tests consist of two parts:

All KASAN tests are integrated with the KUnit Test Framework and can be enabled
via ``CONFIG_KASAN_KUNIT_TEST``. The tests can be run and partially verified
automatically in a few different ways; see the instructions below.
2. Tests that are currently incompatible with KUnit. Enabled with
``CONFIG_KASAN_MODULE_TEST`` and can only be run as a module. These tests can
only be verified manually by loading the kernel module and inspecting the
kernel log for KASAN reports.
Each KUnit-compatible KASAN test prints one of multiple KASAN reports if an
error is detected. Then the test prints its number and status.

There are a few ways to run the KASAN tests.
1. Loadable module
With ``CONFIG_KUNIT`` enabled, KASAN-KUnit tests can be built as a loadable
module and run by loading ``kasan_test.ko`` with ``insmod`` or ``modprobe``.
