  EGL: No-op dma_buf import modifiers on some Mali devices.
  
  Some of the vendor checks in the EGL_EXT_image_dma_buf_import_modifiers
  enablement logic disable the extension on older Mali devices while
  Chrome depends on the presence of this extension, even if the
  implementation is no-op'ed.
  
  Refactor the logic into DisplayEGL with a tri-state:
   * Extension exposed and forwarded to the driver
   * Extension exposed and no-op'ed (Mali)
   * Extension not exposed (ARM)
  
  Bug: angleproject:7664
