Currently, return values of KUnit `#[test]` functions are ignored.
Thus introduce support for `-> Result` functions by checking their
returned values.
At the same time, require that test functions return `()` or `Result<T,
E>`, which should avoid mistakes, especially with non-`#[must_use]`
types. Other types can be supported in the future if needed.
With this, a failing test like:
#[test]
fn my_test() -> Result {
f()?;
Ok(())
}
will output:
[ 3.744214] KTAP version 1
[ 3.744287] # Subtest: my_test_suite
[ 3.744378] # speed: normal
[ 3.744399] 1..1
[ 3.745817] # my_test: ASSERTION FAILED at rust/kernel/lib.rs:321
[ 3.745817] Expected is_test_result_ok(my_test()) to be true, but is false
[ 3.747152] # my_test.speed: normal
[ 3.747199] not ok 1 my_test
[ 3.747345] not ok 4 my_test_suite
