RISC-V: check cfg (batch 1)

Browse source 
rust-lang/rust#138823 added five new extensions as compiler target features.
This commit reflects that fact and now checks static target features on
`std::arch::is_riscv_feature_detected!` as well.

*   "Zicsr"
*   "Zicntr"
*   "Zihpm"
*   "Zifencei"
*   "Zihintpause"
