[compiler-rt][profile][RISCV] Enable profile for RISC-V

[kito-cheng]

Summary

Profile library are written by standard libraries or POSIX calls depend on target support, so there is no porting effort for the target, we could enable that for both RV32 and RV64, verified on the RV64 platform.

Profile library are written by standard libraries, so there is no porting effort for the target,

in standard libraries?

I think this is inappropriate. profile has some #ifdef and uses some POSIX stuff, there is still porting risk, just doesn't affect portability on many architectures including RISC-V.
You may add RISCV32 now. The test can be disabled on RISCV32 if fails.

Changes:

• Also enable for RV32
