Subject: [PATCH v5] kunit: Cover 'assert.c' with tests

There are multiple assertion formatting functions in the `assert.c`
file, which are not covered with tests yet. Implement the KUnit test
for these functions.

The test consists of 11 test cases for the following functions:

1) 'is_literal'
2) 'is_str_literal'
3) 'kunit_assert_prologue', test case for multiple assert types
4) 'kunit_assert_print_msg'
5) 'kunit_unary_assert_format'
6) 'kunit_ptr_not_err_assert_format'
7) 'kunit_binary_assert_format'
8) 'kunit_binary_ptr_assert_format'
9) 'kunit_binary_str_assert_format'
10) 'kunit_assert_hexdump'
11) 'kunit_mem_assert_format'

The test aims at maximizing the branch coverage for the assertion
formatting functions.

As you can see, it covers some of the static helper functions as
well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT'
and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the
corresponding definitions to `assert.h`.

Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to
how it is done for the string stream test.

---
V1 -> V2:
- Check the output from the string stream for containing the key parts
instead of comparing the results with expected strings char by char, as
it was suggested by Rae Moar <rmoar@...gle.com>. Define two macros to
make it possible (ASSERT_TEST_EXPECT_CONTAIN and
ASSERT_TEST_EXPECT_NCONTAIN).
- Mark the static functions in `assert.c` as VISIBLE_IF_KUNIT and export
them conditionally if kunit is enabled instead of including the
`assert_test.c` file in the end of `assert.c`. This way we will decouple
the test from the implementation (SUT).
- Update the kunit_assert_hexdump test: now it checks for presense of
the brackets '<>' around the non-matching bytes, instead of comparing
the kunit_assert_hexdump output char by char.
V2 -> V3:
- Make test case array and test suite definitions static
- Change the condition in `assert.h`: we should declare VISIBLE_IF_KUNIT
functions in the header file when CONFIG_KUNIT is enabled, not
CONFIG_KUNIT_TEST. Otherwise, if CONFIG_KUNIT_TEST is disabled,
VISIBLE_IF_KUNIT functions in the `assert.c` are not static, and
prototypes for them can't be found.
- Add MODULE_LICENSE and MODULE_DESCRIPTION macros
V3 -> V4:
- Compile the assertion test only when CONFIG_KUNIT_TEST is set to 'y',
as it is done for the string-stream test. It is necessary since
functions from the string-stream are not exported into the public
namespace, and therefore they are not accessible when linking and
loading the test module.
V4 -> V5:
- Remove EXPORT_SYMBOL_IF_KUNIT from the assert.c and all of the
module-related macros from the test source since the test can't
be used as a loadable module for now (see V3 -> V4).
