[SVE ACLE] Remove explicit sve2 requirement from crypto and b16b16 builtins.

[paulwalker-arm]

The instructions have no direct dependency on SVE2, nor does the code generator require it.

[paulwalker-arm]

I've removed this RUN line because from a code generation point of view there is nothing new being tested. We already have clang tests to verify the sve2-sm4 alias is correctly expanded.
