[AArch64] Allow SVE_AES instructions in streaming mode with SSVE_AES (#115526)
In accordance with
https://developer.arm.com/documentation/ddi0602/latest/, the following
SVE2 instructions are available in streaming SVE mode if the target has
FEAT_SSVE_AES
- PMULLB, PMULLT (128-bit element)
- AESE (vectors)
- AESD (vectors)
- AESMC
- AESIMC
This patch updates the predication of these instructions to reflect this
architecture change.
Note that the assembler predicates here always require at least one of
sve2,ssve-aes due to the following condition on
[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)
>If FEAT_SVE_AES is implemented, then FEAT_SVE2 or FEAT_SSVE_AES is
implemented.
