0d76b6ef76 Return an error if asking for decrypt under BLOCK_CIPHER_NO_DECRYPT
If MBEDTLS_BLOCK_CIPHER_NO_DECRYPT is enabled, but decryption is
still requested in some incompatible modes, we return an error of
FEATURE_UNAVAILABLE as additional indication.

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.
