aarch64: Add +sve2p1 to -march=armv9.4-a flags
The ArmARM says:
"In an Armv9.4 implementation, if FEAT_SVE2 is implemented, FEAT_SVE2p1
is implemented."
We should enable +sve2p1 as part of -march=armv9.4-a, which this patch does.
This makes gcc consistent with gas.
Bootstrapped and tested on aarch64-none-linux-gnu.

* config/aarch64/aarch64-arches.def (...): Add SVE2p1.
* doc/invoke.texi (AArch64 Options): Document +sve2p1 in
-march=armv9.4-a.
