OpenGL: Don't bind non-existent shader resources.

In OpenGL we have to query a resource's location or index before we can
bind it. The driver can tell us that the resource doesn't exist using
special values (-1 for locations, GL_INVALID_INDEX for indices). This
happens when Dawn compiles a pipeline that has bind group bindings that
none of the shader modules uses.

This was found while enable OpenGL debug output.
