[committed][AArch64] Rename +bitperm to +sve2-bitperm

[Richard Sandiford]

After some discussion, we've decided to rename the +bitperm feature
flag to +sve2-bitperm, so that it's consistent with the other SVE2
feature flags.  The associated internal macros already used
"SVE2_BITPERM", so only the feature flag itself needs to change.

Tested on aarch64-linux-gnu and applied.
