  Add GL_RGBX8_SRGB_ANGLEX and GL_BGRX8_SRGB_ANGLEX formats
  
  If app creates AHB with sRGBX format, and then create a EGLImage,
  Image::initialize() will retrieve the sized format from AHB, which is
  GL_RGBX_ANGLE, and then try to convert to sRGB color space. The bug here
  is that GetNonLinearFormat will pick GL_SRGB8 for all these formats
  :GL_RGB8, GL_BGRX8_ANGLEX, GL_RGBX8_ANGLE. This means that different
  AHBS with these three different format will end up createing a tetxure
  with same format which sRGB. I think the reason somone did it this way
  initially simply because there is no sRGB corresponding format available
  for BGRX8 and RGBX8. This CL adds sRGB internal version of these two
  formats, thus make it straight forward to pick the correct sRGB format.
  
  The other change here is for AHBs, right now we are always force
  mRequiredImageAccess to be Renderable. This actually workedaround the
  bug that mentioned earlier that we are picking the wrong format. Because
  of forced renderable, we end up with SRGB fallback to SRGBA. But
  external images should not fallback, we should use its existing format
  as is since it can be accessed via AHB interface directly.
