When CONFIG_KUNIT is not enabled, __kunit_fail_current_test() an empty
static function.
But GCC complains about unused static functions, *unless* they're static
inline. So add inline to make GCC happy.

Add a kunit_fail_current_test() function to fail the currently running
test, if any, with an error message.
This is largely intended for dynamic analysis tools like UBSAN and for
fakes.
E.g. say I had a fake ops struct for testing and I wanted my `free`
function to complain if it was called with an invalid argument, or
caught a double-free. Most return void and have no normal means of
signalling failure (e.g. super_operations, iommu_ops, etc.).
Key points:
* Always update current->kunit_test so anyone can use it.
* commit 83c4e7a036 ("KUnit: KASAN Integration") only updated it for
CONFIG_KASAN=y
* Create a new header <kunit/test-bug.h> so non-test code doesn't have
to include all of <kunit/test.h> (e.g. lib/ubsan.c)
* Forward the file and line number to make it easier to track down
failures
* Declare the helper function for nice __printf() warnings about mismatched
format strings even when KUnit is not enabled.
Example output from kunit_fail_current_test("message"):
