[vulkan] Set the features on first connection

bug: 111137294
bug: 121377497

This CL introduces a mechanism for Vulkan ResourceTracker to become
aware of what host-side features are available. On the first connection,
we father the feature strings and set feature fields, and this should be
communicated to Vulkan as well.
