Now that this feature has a standard identifier, Darwin has started exposing it accordingly, in addition to the existing less-standard way. Check both, and enable the `crc` feature if either identifier for it is present to ensure backwards and forwards compatibility.

std_detect: RISC-V: implement implication to "C"
Just like we implemented relatively complex rules to imply other extensions **from** "C" (and some others), this commit implements implication **to** the "C" extension from others, complying the following text in the ISA Manual (although there's no direct imply/depend references).
> The C extension is the superset of the following extensions:
>
> - Zca
> - Zcf if F is specified (RV32 only)
> - Zcd if D is specified
This is formally verified so that no other extension combinations (*not* in this implementation) can (currently) imply the "C" extension.
Note: this is a `std_detect` change and not main target feature handling.

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.
