[gpu] Simplify OzoneImageGLTexturesHolder logic

Simple OzoneImageGLTexturesHolder logic by passing the SharedImageFormat
and plane index instead of BufferFormat and BufferPlane and handling
single/multi plane logic where the NativePixmapGLBinding is created.

This also helps eliminate last caller of gfx::BufferFormatIsMultiplanar
and thus removes the utility method as well.
