selftests: Test RISC-V Vector's first-use handler
This add a test to check if the kernel zero-initializes all V registers
after the first-use trap handler returns.
If V registers are not zero-initialized, then the test should fail one
out of several runs:
```
root@sifive-fpga:~# ./v_initval_nolibc
# vl = 256
not ok 1 detect stale values on v-regesters
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 4c 41 4e 47 3d 43 0 50 41 54 48 3d 2f 75 73
72 2f 6c 6f 63 61 6c 2f 73 62 69 6e 3a 2f 75 73
72 2f 6c 6f 63 61 6c 2f 62 69 6e 3a 2f 75 73 72
ff ff 81 0 0 0 0 0 0 0 0 0 0 0 0 0
```
Otherwise, the test passes without errors each run.
