RFR: 8322179: RISC-V: Implement SHA-1 intrinsic [v5]

[Hamlin Li]

> Hi,
> Can you review this patch to implement SHA-1 intrinsic for riscv?
> Thanks!
> 
> 
> ## Test
> 
> ### Functionality
> 
> tests under `test/hotspot/jtreg/compiler/intrinsics/sha`
> tests found via `find test/jdk -iname "*SHA1*.java"`
> 
> ### Performance
> 
> tested on `T-HEAD Light Lichee Pi 4A`
> 
> JMH_PARAMS="-f 1 -wi 10 -i 20" // for every loop of jmh test
> 
> benchmark tests `MessageDigests.java GetMessageDigest.java MessageDigestBench.java MacBench.java` which are under `test/micro/org/openjdk/bench/`, more spcifically `TESTS="MessageDigests.digest MessageDigests.getAndDigest MessageDigestBench.digest"`

> The data is not stable for test getAndDigest when size == 64, which I think is introduced by  j.s.MessageDigest.getInstance itself, which we don't touch in this patch.
