feat: add ability to define poster props as Image type and render poster as custom component

[moskalakamil]

Summary

I added the ability for the user to fully manage the poster, including: managing all props, rendering their own poster, and fixed a bug with displaying the poster

Closes #3013

Motivation

Issue

Changes

• Added posterProps to allow user manage all of the poster props (incl. source, resizeMode and all others)
• Added renderPoster props, to allow user render poster as a component
• Update docs
• Fixed bug -> When the video wasn't fully loaded but its image was visible, both the video and the poster were simultaneously visible.

Test plan

Run basic example ;)

Overall looks good but let's make it so we don't introduce breaking changes
