aarch64: Test TARGET_STREAMING instead of TARGET_STREAMING_SME
g:ede97598e2c recorded separate ISA requirements for streaming
and non-streaming mode. The premise there was that AARCH64_FL_SME
should not be included in the streaming mode requirements, since:
(a) an __arm_streaming_compatible function wouldn't be in streaming
mode if SME wasn't available.
(b) __arm_streaming_compatible functions only allow things that are
possible in non-streaming mode, so the non-streaming architecture
is enough to assemble the code, even if +sme isn't enabled.
(c) we reject __arm_streaming if +sme isn't enabled, so don't need
to test it for individual intrinsics as well.
Later patches lean into this further.
This patch applies the same reasoning to the .md constructs for
base streaming-only SME instructions, guarding them with
TARGET_STREAMING rather than TARGET_STREAMING_SME.
