Remove duplicate play button

[lkcv]

Pull Request Description

Removes the big desktop-only play button in the middle of the screen that persists regardless of mouse panning.
There's already a play/pause button at the bottom control bar, so now it has tooltips depending on the playback state (Pause video and Resume video).

Issue Being Fixed

I haven't created an issue for it yet, but will if needed.

I kind of like the play button in the middle. If the video is paused windowed and there's no mouse focus on the player it's a good indicator the player is in a pause state. Also more UI friendly to older folks when teaching them how to use app.

@talynone, I was trying to make it more like the mobile apps since those only show the single Play/Pause button at the bottom whether the screen is touched or not during playback. I also don't like the icon in the middle 😆

I can add it behind an option, but I'll wait until PartyDonut has a chance to review it.

Like @talynone mentioned, I like having a pause button in the middle as a indicator that it's actually paused.

So closing this for now. Feel free to open a discussion however for any UI/UX ideas.
