Update comments in config.h
...
Some comments in config.h were old. Time for a refresh.
Switch from CRYPTOPP_BOOL_ARM64 to CRYPTOPP_BOOL_ARMV8. Aarch32 is ARMv8, and that's the important part.

Remove Simon and Speck ciphers (GH #585 )
...
We recently learned our Simon and Speck implementation was wrong. The removal will stop harm until we can loop back and fix the issue.
The issue is, the paper, the test vectors and the ref-impl do not align. Each produces slightly different result. We followed the test vectors but they turned out to be wrong for the ciphers.
We have one kernel test vector but we don't have a working implementation to observe it to fix our implementation. Ugh...
