openvr Feature Request: Compositor->GetVulkanInstanceExtensionsRequired without Init

What I would like, is for Compositor->GetVulkanInstanceExtensionsRequired to be callable without initialising OpenVR, in the same manner as VR_IsHmdPresent() and VR_IsRuntimeInstalled().

I've got a program that while it does support VR, it is not required to run it. I'd like to initialise Vulkan with any extensions that OpenVR wants, so that later on if the user wants to use the HMD for something, I don't have to shut down Vulkan and re-initialise it. I'd also like to get the extension names without having to wait for SteamVR to load in the event of a cold start, so that my program can still initialise without any perceptible delays.

An equivalent of Compositor->GetVulkanDeviceExtensionsRequired would be nice too :-)
