Description
As part of my work on Vello, I have been optimising our startup time on Android.
One significant aspect of this is Vulkan pipeline caching.
This branch is a checkpoint of a non-idiomatic implementation of this pipeline caching, allowing us to validate that we require wgpu to provide pipeline caching.
Testing
I ran this on Wayland Vulkan (without the env var being provided), and on Android Vulkan (with the env var set)
