6369621e79 add Hygon Dhyana CPU Vendor ID("HygonGenuine") checking 
As Hygon Dhyana originates from AMD technology and shares most of the architecture with
AMD's family 17h, but with different CPU Vendor ID("HygonGenuine")/Family series number(Family 18h).

for CPUID feature bits, Hygon Dhyana(family 18h) share the same definition with AMD family 17h.
AMD CPUID specification is https://www.amd.com/system/files/TechDocs/25481.pdf.

11c624e488 Refactor stdsimd 
This commit:

* renames `coresimd` to `core_arch` and `stdsimd` to `std_detect`

* `std_detect` does no longer depend on `core_arch` - it is a freestanding
  `no_std` library that only depends on `core` - it is renamed to `std_detect`

* moves the top-level coresimd and stdsimd directories into the appropriate
  crates/... directories - this simplifies creating crate.io releases of these crates

* moves the top-level `coresimd` and `stdsimd` sub-directories into their
  corresponding crates in `crates/{core_arch, std_detect}`.
