selftests: riscv: Fix vector tests Overhaul the riscv vector tests to use kselftest_harness to help the test cases correctly report the results and decouple the individual test cases from each other. With this refactoring, only run the test cases if vector is reported and properly report the test case as skipped otherwise. The v_initval_nolibc test was previously not checking if vector was supported and used a function (malloc) which invalidates the state of the vector registers.
