[AArch64] Rename +bitperm to +sve2-bitperm

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.

	* doc/c-aarch64.texi: Remame the +bitperm extension to +sve2-bitperm.
