The WebGL spec proposal was changed so that only GL_OVR_multiview
extension name is supported, instead of having two variants
OVR_multiview and OVR_multiview2. We're only supporting the WebGL
version of the shader extension, so we drop compiler support for
GL_OVR_multiview2. Shader restrictions were also removed from the
WebGL spec, so no special validation for how ViewID_OVR gets used is
needed.

Tests that were testing for the shader restrictions are either removed
or changed from negative tests to positive tests.

The calculation for unreferenced was incorrect - it checked the 'used'

all the unused uniforms were to be considered valid samplers. Instead,
initialize the uniform index to INVALID_INDEX.

Until this patch multi-view layered framebuffers used to be cleared by
attaching a single layer of each attachment to a framebuffer and calling
the Clear* command for that internal framebuffer.
According to the GL 4.1+ specifications, Clear* commands clear all of
the layers of an attached 2D texture array. If all of the layers are
active for a multi-view layered framebuffer, then we can directly call
the corresponding Clear* command instead of iterating over each layer
and clearing it.
