Improvements to the video player lock

Description

Right now, the video player lock is a 2 state button, either rotation is locked (except when inverting landscape so that that the image isn't upside down), or it is not, and the user is free to rotate the video (whether rotation is enabled on it's device or not).

Expected behavior

Some users have requested a way to force the lock in:

• Landscape (whether that is the position of the phone when locking or not)
• Portrait (whether that is the position of the phone when locking or not)
• To lock the screen with the current screen rotation

Lastly some user complained that in the current implementation, when locked in landscape, the video would invert so that the video wouldn't be upside down

To avoid having to cycle through like we used to with aspect ratios, the same dialog could be expanded and split in two to have on the left the different locks available, and on the right the different aspect ratios.
