[video] add fullscreen enter and exit events

[fobos531]

Why

Adds fullscreen enter/exit events across all platforms. Motivated by bluesky-social/social-app#4907, therefore credits to @haileyok

How

Just followed the original implementation from Hailey, with small difference being the naming of the actual event which follows the PiP event naming, as well support added on web.

Test Plan

Untested on web & apple TV.

Looks good 😄 Thank you!

They are VideoView events, not VideoPlayer events 😉 You can remove this (and rebuild files).

Suggested change

	/**
	* Handler for an event emitted when the player enters the fullscreen mode.
	*/
	onFullscreenEnter(): void;
	/**
	* Handler for an event emitted when the player exits the fullscreen mode.
	*/
	onFullscreenExit(): void;

Hey @tsapeta , that makes sense. I believe just removing this is not enough and that it needs to be added to the VideoView.web.tsx, like so: 59fdd57 (#30922)

I followed @behenate 's PIP implementation as seen here: https://github.com/expo/expo/pull/30524/files#diff-72705cdf87b0dfe8ecd5783a1ffd65f9e6257b81e046c967f4535b75b89c9835R74

Let me know if this looks good and whether anything else needs to changed
