Handle loss of WebGL context

[wouterlucas]

Seems newer Chrome >123 versions will pull the WebGL context, this was raised in a previous L2 issue where we stated coming up with such a solution would be hard with the state of the L2 code being what it is. However we should experiment with ways to do so in L3.

Assuming:

• We get an event that the WebGL context is lost
• We get an event that its back available again, like onfocus or similar
• We can reinitialize our shader programs / glw wrapper and resume rendering
• Notify the app dev framework this has happened accordingly

Moved over from an original L2 issue:
rdkcentral/Lightning#469

More importantly this particular comment:
