gpu: Change Produce/ConsumeTexture to allow texture sharing
This changes the semantics of ProduceTexture to not replacing the current texture by a dud, but instead keeping the existing one, that it also puts into the mailbox. It changes the semantics of ConsumeTexture to deleting the current texture, and replacing it by the mailbox contents (without taking it out of the mailbox). The texture becomes shared. The mailbox is now effectively a weak pointer onto the texture.
BUG=230137
