Assumes WebGLObjects are extensible and include an Object prototype

[estobbart]

The spec doesn't seem to be very clear on WebGLObjects.
But w/ WebGLTexture objects, Lightning attempts to assign it's own properties..

https://github.com/rdkcentral/Lightning/blob/master/src/renderer/webgl/WebGLRenderer.mjs#L217-L218

Here it uses a WebGLTexture to call hasOwnProperty
https://github.com/rdkcentral/Lightning/blob/master/src/tree/TextureManager.mjs#L123

This seems to not be a problem with most browser implementations, but could be an issue with more esoteric platforms.

Wanted to get feedback on this prior to any contribution.
