docs: GL_ARB_compute_shader is not a ES extension

Browse source 
Without this commit, GL_ARB_compute_shader appears as both an OpenGL
and an OpenGL ES extension.

But this is not an OpenGL ES extension. One of the main differences is
that the minimum value for WORK_GROUP_INVOCATIONS on
GL_ARB_compute_shader is 1024, while the minimum value required for
the OpenGL ES 3.1 spec is 128. So for example, both v3d and panfrost
doesn't expose ARB_compute_shader, while it supports compute shader on
OpenGL 3.1, so the docs are wrong.

I guess that the reason of re-using ARB_compute_shader is because
there isn't an OES compute shader extension. There was an EXT
extension though, so this is similar to geometry shader, where there
you had ARB_geometry_shader4, but it was superseded by OpenGL
3.2. This commit follows geometry shader approach, and just adds a
"Compute shader" feature on OpenGL ES 3.1
