Arm64: simplify Crypto arch extension handling

Browse Source 
This, at the assembler level, is just a "brace" feature covering both
AES and SHA2. Hence there's no need for it to have a separate feature
flag, freeing up a bit for future re-use. Along these lines there are
also a number of dead definitions/variables in the opcode table file.
