Use TransferableResource::Make in exo

Metadata for zero-copy path:
* Format -- Used to be format_, same as we passed to Texture ctor.
* texture_target -- was already from shared image.
* is_overlay_candidate -- comes from bool, so we override it for now.

Metadata for copy path:
* Format -- hardcoded to RGBA8888 for both.
* texture_target -- used to be always 2D, that would match
  ClientSharedImage for single plane formats [1].
* is_overlay_candidate -- was always false, now matches the absence of
  SCANOUT usage for SharedImage.

Metadata for both:
* Size -- Used to come from GetSize(), same is passed to Texture ctor
  and CreateSharedImage call.
* origin, alpha_type -- both rely on default values, which is premul
  top-left both for SharedImage and TransferableResource.
* color_space -- this wasn't set before, now it's set from shared image,
  but caller always overwrites it [2]. We'll deal with it in the
  follow-up.
