Rollup merge of #145417 - a4lg:riscv-arch-platform-guide-ch2, r=Amanieu
std_detect: RISC-V platform guide documentation This is practically a revert of a revert, making the commit e907456b2e10622ccd854a3bba8d02ce170b5dbb on `stdarch` come around again with minor fixes, enhancements and adjustments. An excerpt from the original commit message follows: Since there's no architectural feature detection on RISC-V (unlike `CPUID` on x86 architectures and some system registers on Arm/AArch64), runtime feature detection entirely depends on the platform-specific facility. As a result, availability of each feature heavily depends on the platform and its version. To help users make a decision for feature checking on a RISC-V system, this commit adds a platform guide with minimum supported platform versions.
