RISC-V: Rearrange the test files for vector SAT_TRUNC [NFC]

RISC-V: Rearrange the test files for vector SAT_TRUNC [NFC]

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

Meanwhile, moved all related test files to riscv/rvv/autovec/sat/.

It is test only patch and obvious up to a point, will commit it
directly if no comments in next 48H.
