compilert-rt: build out-of-line LSE atomics helpers for aarch64
Both clang >= 12 and gcc >= 10.1 now default to -moutline-atomics for aarch64. This requires a bunch of helper functions in libcompiler_rt.a, to avoid link errors like "undefined symbol: __aarch64_ldadd8_acq_rel". (Note: of course you can use -mno-outline-atomics as a workaround too, but this would negate the potential performance benefit of the faster LSE instructions.) Bump __FreeBSD_version so ports maintainers can easily detect this. PR: 257392 MFC after: 2 weeks
