What's new in version 6.5

This release includes the following significant changes:

API additions

Added BoundedPlaneBuilder.WithPose overload that takes an OpenXR XrPosef if your app uses OpenXR Plug-in 1.16.0 or newer.
Added XRAnchorBuilder.FromAnchor, which enables you to initialize all fields of an XRAnchorBuilder from a given anchor.
Added XRResultStatus.StatusCode.NotFound and XRResultStatus.StatusCode.NotTracking as a new possible error codes for AR Foundation operations.
Added an implicit operator to convert from XrUuid to SerializableGuid if your project uses OpenXR Plug-in 1.16.0 or newer.
Added an IEquatable<XrUuid> implementation to SerializableGuid if your project uses OpenXR Plug-in 1.16.0 or newer.
Added XRResultStatus.HasNativeStatusCode as a convenience method to determine whether a native status code is present.

Changed SubsystemLifecycleManager.OnEnable to poll for a number of seconds until a subsytem is created before it disables itself, allowing subsystems to be created asynchronously and still connect with their managers.

Deprecated and replaced the following properties of XRPlaneSubsystemDescriptor.Cinfo to allow providers to determine at runtime whether AR Foundation plane APIs are supported:
- supportsBoundaryVertices to supportsBoundaryVerticesDelegate
- supportsClassification to supportsClassificationDelegate
