core: add accelerated SHA-256 routines

Adds an Arm CE accelerated SHA-256 function to core/arch/arm/crypto. The
code originates from the previous implementation inside LTC library.
With this multiple crypto libraries can share the function.

The old CFG_CRYPTO_SHA256_ARM64_CE and CFG_CRYPTO_SHA256_ARM32_CE are
replaced by CFG_CRYPTO_SHA256_ARM_CE.

CFG_CORE_CRYPTO_SHA256_ACCEL is introduced as to indicate that some kind of
SHA-256 acceleration is available, not necessarily based on Arm CE.
