  [clang][aarch64] Drop experimental from  __ARM_FEATURE_SVE_BITS macro

The __ARM_FEATURE_SVE_BITS feature macro is specified in the Arm C
Language Extensions (ACLE) for SVE [1] (version 00bet5). From the spec,
where __ARM_FEATURE_SVE_BITS==N:

    When N is nonzero, indicates that the implementation is generating
    code for an N-bit SVE target and that the arm_sve_vector_bits(N)
    attribute is available.

This was defined in D83550 as __ARM_FEATURE_SVE_BITS_EXPERIMENTAL and
enabled under the -msve-vector-bits flag to simplify initial tests.
This patch drops _EXPERIMENTAL now there is support for the feature.
