plume currently faces resource corruption issues in some workloads, like N64 recompiles using RT64, when residency sets are enabled. This PR takes the heavy-handed approach of tracking all resources in a device-level residency set that we can bind to each queue. We were already doing this for GPU addressable resources, this just expands it to cover all resources.
This is the approach currently taken by Vulkan-on-Metal implementations, since the Vulkan memory model seems to assume that all resources are always GPU-resident, so it's a strategy that's proven to work fine. This also avoids issues where using more than 32 descriptor sets large enough to trigger the use of residency sets would exceed Metal's limit of residency sets per command buffer.
