[AArch64][SVE2] Guard while intrinsics on scalar bfloat feature macro
Summary:
`svwhilerw_bf16` and `svwhilewr_bf16` intrinsics use the scalar
`bfloat16_t`
type which is predicated on `__ARM_FEATURE_BF16_SCALAR_ARITHMETIC`. This
patch changes the feature guard from `__ARM_FEATURE_SVE_BF16` to the
scalar bfloat feature macro.
The verify tests for `+bf16` are also removed in this patch. The purpose
of these checks was to match the SVE2 ACLE tests that look for an
implicit declaration warning if the feature isn't set. They worked when
the intrinsics were guarded on `__ARM_FEATURE_SVE_BF16` as the
`bfloat16_t`
was guarded on a different macro, but with both the type and intrinsic
guarded on the same macro an earlier error is triggered in the ACLE
regarding the type and we don't get a warning as we do for SVE2.
