wolfssl: enable CPU crypto instructions

Browse Source 
This enables AES & SHA CPU instructions for compatible armv8, and x86_64
architectures.  Add this to the hardware acceleration choice, since they
can't be enabled at the same time.

The package was marked non-shared, since the arm CPUs may or may not
have crypto extensions enabled based on licensing; bcm27xx does not
enable them.  There is no run-time detection of this for arm.

NOTE:
Should this be backported to a release branch, it must be done shortly
before a new minor release, because the change to nonshared will remove
libwolfssl from the shared packages, but the nonshared are only built in
a subsequent release!

This will use Intel AESNI insturctions or armv8 Crypto Extensions.
Either of them should easily outperform hardware crypto in WolfSSL.
