  [DAG][AArch64] Support masked loads/stores with nontemporal flags (#87608)

SVE has some non-temporal masked loads and stores. The metadata coming
from the nodes is not copied to the MMO at the moment though, meaning it
will generate a normal instruction. This patch ensures that the right
flags are set if the instruction has non-temporal metadata.
