Exposed support for dynamically enabling extensions in command buffer
implementation via new glGetRequestableExtensionsCHROMIUM and
glRequestExtensionCHROMIUM entry points. These entry points are needed in
order to allow WebGL to both query the available extensions and enable them
individually.
Added these entry points to WebGraphicsContext3DCommandBufferImpl. A
subsequent WebKit checkin under https://bugs.webkit.org/show_bug.cgi?id=40316
will utilize them and implement the OES_texture_float extension for WebGL.
BUG=none
TEST=none (ran with new oes-texture-float.html WebGL conformance test)
