Subject : Stop using GrTexture::get/setCustomData in Canvas2DLayerBridge
Author  : junov
Commit description:
  
Canvas2DLayerBridge was using custom data to cache mailbox names
associated with recycled textures managed by skia.  This helped
prevent leaking mailboxes.  This CL uses a different approach
that consists in disassociating mailboxes to prevent the mailbox
leak.  The goal is to allow the skia team to proceed with the
deprecation of texture custom data attachments.
