aarch64: PR target/115475 Implement missing __ARM_FEATURE_SVE_BF16 macro
The ACLE requires __ARM_FEATURE_SVE_BF16 to be enabled when SVE and BF16
and the associated intrinsics are available.
GCC does support the required intrinsics for TARGET_SVE_BF16 so define
this macro too.
Bootstrapped and tested on aarch64-none-linux-gnu.

Define __ARM_FEATURE_SVE_BF16 for TARGET_SVE_BF16.
