System property for hand tracking mesh.
Description

If a runtime returns FALSE for supportsHandTrackingMesh, the system does not support hand tracking mesh input, and therefore must return ERROR_FEATURE_UNSUPPORTED from CreateHandMeshSpaceMSFT and UpdateHandMeshMSFT. The application should avoid using hand mesh functionality when supportsHandTrackingMesh is FALSE.

If a runtime returns TRUE for supportsHandTrackingMesh, the system supports hand tracking mesh input. In this case, the runtime must return a positive number for maxHandMeshIndexCount and maxHandMeshVertexCount. An application should use maxHandMeshIndexCount and maxHandMeshVertexCount to preallocate hand mesh buffers and reuse them in their render loop when calling UpdateHandMeshMSFT every frame.
