Draft: tu: Minor misc Android improvements
What does this MR do and why?
The first commit limits the advertised Vulkan version on Android to 1.1, which is maximum that the Vulkan loader on Android prior to 13 supports. Not sure why this hasn't come up before, but I don't think we should be exposing 1.3 on earlier Android version.
The second commit fixes the ugralloc never getting cleaned up. I verified that it's now properly getting cleaned up and that it was lingering before.
Third patch is a no-op and the fourth one is for debugging only.
