aarch64: reorder: add Acdb8a/Acdb4a and check for SVE availability when necessary

[renato-arantes]

Description

1. It fixes the test_reorder test by checking whether the target supports SVE instructions before executing a reorder that uses SVE intrinsics.
2. It also adds Acdb8a and Acdb4a formats to the possible target reorder memory formats.

General

• Do all unit and benchdnn tests (make test and make test_benchdnn_*) pass locally for each commit?
• Have you formatted the code using clang-format?

Thanks @renato-arantes.

• Could you run clang format on your patch please?
• could you change the commit message to adhere to oneDNN contribution guidelines ? Something like aarch64: reorder: add Acdb8a/Acdb4a and check for SVE availability when necessary should do
