kunit: Don't crash if no parameters are generated

It's possible that a parameterised test could end up with zero
parameters. At the moment, the test function will nevertheless be called
with NULL as the parameter. Instead, don't try to run the test code, and
just mark the test as SKIPped.

kunit: Reset suite count after running tests

There are some KUnit tests (KFENCE, Thunderbolt) which, for various
reasons, do not use the kunit_test_suite() macro and end up running
before the KUnit executor runs its tests. This means that their results
are printed separately, and they aren't included in the suite count used
by the executor.

This causes the executor output to be invalid TAP, however, as the suite
numbers used are no-longer 1-based, and don't match the test plan.
kunit_tool, therefore, prints a large number of warnings.

While it'd be nice to fix the tests to run in the executor, in the
meantime, reset the suite counter to 1 in __kunit_test_suites_exit.
Not only does this fix the executor, it means that if there are multiple
calls to __kunit_test_suites_init() across different tests, they'll each
get their own numbering.

kunit_tool likes this better: even if it's lacking the results for those
tests which don't use the executor (due to the lack of TAP header), the
output for the other tests is valid.

kunit: Print test statistics on failure

When a number of tests fail, it can be useful to get higher-level
statistics of how many tests are failing (or how many parameters are
failing in parameterised tests), and in what cases or suites. This is
already done by some non-KUnit tests, so add support for automatically
generating these for KUnit tests.

This change adds a 'kunit.stats_enabled' switch which has three values:
- 0: No stats are printed (current behaviour)
- 1: Stats are printed only for tests/suites with more than one
subtest (new default)
- 2: Always print test statistics

For parameterised tests, the summary line looks as follows:
" # inode_test_xtimestamp_decoding: pass:16 fail:0 skip:0 total:16"
For test suites, there are two lines looking like this:
"# ext4_inode_test: pass:1 fail:0 skip:0 total:1"
"# Totals: pass:16 fail:0 skip:0 total:16"

The first line gives the number of direct subtests, the second "Totals"
line is the accumulated sum of all tests and test parameters.

This format is based on the one used by kselftest[1].
