This fixes #693.

This fixes #680

The previously used workaround that was needed for iOS 8 and the 32bit
Intel iOS simulator caused low level and hard to reproduce threading
issues.

This MR restricts the use of the work-around to the 32bit Intel
simulator and deploys thread_local everywhere else.

This raises the deployment target from iOS 8.4 to 9.0 matching the
official VLC-iOS version.

By default, only 64bit slices will be compiled. For the CI and
releases, we still build all the things.

This is a backport of !258

VLCMediaPlayer: Deprecated previous equalizer related handling and replaced internal handling for consistency with new handling

Hank Anderson authored 2 years ago and Felix Paul Kühne committed 2 years ago

VLCMediaPlayer: Fixed a bug that setAmplification:forBand: was not reflected and fixed a problem that the equalizerEnabled flag was out of sync

The class and the associated protocol was previously not exposed on
macOS as part of the umbrella header while the header itself was
shipped, so the API was hidden from swift relying on the module map.

Additionally, this reorders the header content to make it easier to
compare with the iOS counterpart.

This also deprecates the existing implementation but leaves it in place.
