[AArch64] Reduce +sve2-aes to an alias of +sve-aes+sve2 (llvm#114293)
This patch introduces the amended feature flag for [FEAT_SVE_AES](https://developer.arm.com/documentation/109697/2024_09/Feature-descriptions/The-Armv9-0-architecture-extension?lang=en#md457-the-armv90-architecture-extension__feat_FEAT_SVE_AES), '**sve-aes**'. The existing flag associated with this feature, 'sve2-aes' must be retained as an alias of 'sve-aes' and 'sve2' for backwards compatibility. The [ACLE](https://github.com/ARM-software/acle/blob/main/main/acle.md#aes-extension) documents `__ARM_FEATURE_SVE2_AES`, which was previously defined to 1 when > there is hardware support for the SVE2 AES (FEAT_SVE_AES) instructions and if the associated ACLE intrinsics are available. The front-end has been amended such that it is compatible with +sve2-aes and +sve2+sve-aes.
