This commit enables the AArch64 SVE AES instructions (AESE, AESD, AESMC, AESIMC) to function in Streaming SVE mode, by leveraging the FEAT_SSVE_AES feature. The changes involve updating CPP builtins, DEF files, and model files to correctly identify and utilize these AES instructions in their streaming-compatible form. Tests are also updated to reflect this new capability.
