Reverts #50028
Initiated by: jonahwilliams
This change reverts the following previous change:
Original Description:
Once a hardware buffer has been imported (a VkImage created for it), we don't ever need to re-create a VkImage, even when the contents change. The same hardware buffer can be identified by ID. Part of flutter/flutter#142153

Otherwise we spend a lot of time re-creating VkImages:

Draft is here, but is currently leaky: #50028
We only need something like a LRU with the max image size (seems to be 3 for me). This does log locally that I'm not calling close correctly:
