In the macros DO_SVE2_RRX and DO_SVE2_RRX_TB we use the
feature check aa64_sve, thus exposing this set of instructions
in SVE as well as SVE2. Use aa64_sve2 instead, so they UNDEF
on an SVE1-only CPU as they should.

Strictly, the condition here should be "SVE2 or SME"; but we
will correct that in a following commit with all the other
missing "or SME" checks.
