Fixes in particular the space transform submitted in composition layers
in local reference space.
Consider a pose given with a pose offset to an XrSpace as its origin.
To construct the Pose in global space, simply add up XrSpace pose in
global space, XrSpace pose offset and the given pose.

The overrides didn't do anything unless Monado was compiled for
in-process, and even then the device might return a differnt fov.
The todo was for a driver and shouldn't be in the state tracker.
Usually renderdoc captures frames by hooking the present functions to
recognize when an application is finished rendering a frame.
OpenXR applications might not present to a window. Therefore use the
renderdoc API to capture application frames between xrBeginFrame and
and xrEndFrame.
This allows renderdoc to capture application frames without the need
to modify the application.
oxr_instance::oxr_interaction_profile is used to bind interaction profiles
available on the assigned device to interaction profiles suggested by the
application.
Creating an interaction profile that has not been suggested might interfere
with the binding code.
xrGetInputSourceLocalizedName can only be called after the action sets are
attached, meaning all the interaction profiles must have already been
suggested.

Apparently the gl_xlib backend really depends on GLX specifically, so
fix the issue by reflecting that in the conditionally compiled blocks.
This matches the OpenXR usage: the array is the plural of the element type,
and the count is the singular element type plus "count" (usually CountOutput
because of the two-call idiom)
Includes fixes to other code to match API changes.
We now have a cmake-format config file.
We no longer use list variables for sources, instead using
target_sources when we need to add, in accordance with current
best practice. (This makes it a lot easier to edit too.) There's no more
include_directories(), add_definitions(), or other gently-deprecated
directory-scoped commands, nor any CMake scripts that include
a parent directory reference (named targets instead)
The hardcoded value 32 was actually wrong and caused a warning

The STOPPING state has two possible follow up paths:
STOPPING -> IDLE -> READY
STOPPING -> IDLE -> EXITING
After EXITING, the application must call xrDestroySession; there is no meaningful
session state after EXITING.
To go to the READY state again, the application should first create a new session.
Applications that are lazy and drain the entire event queue and only handle
the last encountered state would be affected by "skipping" the EXITING state.
XR_KHR_vulkan_enable2:
physicalDevice VkPhysicalDevice must match the device specified by xrGetVulkanGraphicsDevice2KHR
XR_KHR_vulkan_enable:
physicalDevice VkPhysicalDevice must match the device specified by xrGetVulkanGraphicsDeviceKHR
XR_KHR_vulkan_enable:
Add a trivial check that xrGetVulkanGraphicsDeviceKHR is called before xrCreateSession.
(our cached suggested device will be XR_NULL_HANDLE if it has not been called).
The XR_KHR_vulkan_enable2 code path already contains this check.
