arm64: realm: Move Realm memory encryption ops to RSI code

Realm memory encryption callbacks are CCA-specific. Keep the Realm callback
registration with the RSI initialization code instead of pageattr.c, which
only needs to provide the low-level page-attribute transition helper.

Export __set_memory_enc_dec() within arm64 so the RSI code can wrap it with
the Realm-specific encrypt/decrypt callbacks and warning policy.

No functional changes in this patch.
