RISC-V: Rearrange the test files for scalar SAT_ADD [NFC]

RISC-V: Rearrange the test files for scalar SAT_ADD [NFC]

The test files of scalar SAT_ADD only has numbers as the suffix.
Rearrange the file name to -{form number}-{target-type}.  For example,
test form 3 for uint32_t SAT_ADD will have -3-u32.c for asm check and
-run-3-u32.c for the run test.

The below test suites are passed for this patch.
* The rv64gcv fully regression test.
