Implement new WEBGL compressed texture extensions

Implement new WEBGL compressed texture extensions
https://bugs.webkit.org/show_bug.cgi?id=77066

Source/WebCore:

This removes the old experimental compressed
texture extension and implements the first new
one.

A test is in the WebGL conformance tests in
extensions/webgl-compressed-texture-s3tc.html
and will be copied here in a future patch.
