0d4f4e5b01 Add option to disable built-in aes implementation. 
For time being, there are only two aes implementations for known
architectures. I define runtime detection function as const when
built-in was disabled. In this case, compiler will remove dead
built-in code.

aa4f621901 aesce: use correct target attribute when building with clang 
Seems clang has its own issues when it comes to crypto extensions,
and right now the best way to avoid them is to accurately enable
the needed instructions instead of the broad crypto feature.

E.g.: https://github.com/llvm/llvm-project/issues/61645

471a975942 aesce: do not specify an arch version when enabling crypto instructions 
Building mbedtls with different aarch64 tuning variations revealed
that we should use the crypto extensions without forcing a particular
architecture version or core, as that can create issues.
