fix: Guard against Safari adding native controls after fullscreen

[mister-ben]

Description

Sometimes iOS Safari enabled native controls on the video el when existing fullscreen, resulting in both the native controls and Video.js controls being visible. Fixes #3762

Specific Changes proposed

• Set controls to false on the tech el when iOS exits fullscreen, as long as nativeControlsForTouch is not being used.
• Not pertinent to the double controls issue, but also fixes the behaviour of the vjs-ios-native-fs, which is currently toggling when entering fullscreen and remaining as is on exiting fullscreen. (Although this class may be able to be removed altogether if it wasn't being applied as intended anyway).

Requirements Checklist

  • Change has been verified in an actual browser (Chrome, Firefox, Safari)
