Hide symbols names when building for mac/arm64

This matches the .hidden already used for ELF outputs.

This is needed for Chromium's mac/arm64 build. Chromium has a build step that verifies that Chromium Framework only exports a small, fixed set of symbols. The dav1d symbols showed up unexpectedly. This fixes that.

That red pipeline report looks like something unrelated to this patch.

LGTM

Oh, we have a similar .hidden further down in the const macro, that we probably should update accordingly. We don't currently use that within dav1d, but rav1e (which imports our asm) does.

Compare with previous version

Mind if I do that in a separate pull merge request? We're actively blocked on getting this one in, so I'd like to get this in and update dav1d in our repo.

Fair enough, let's merge this one first then.
