Common handle requirement missing for nested structs

[Timbals]

In the Valid Usage (Implicit) of XrCompositionLayerCubeKHR it says "Both of space and swapchain must have been created, allocated, or retrieved from the same XrSession"

But for the other types of composition layers, this validity requirement is missing.
This seems like an oversight.

This is presumably because the handles in the other layers are not contained in the layer struct directly, but in a different (nested) struct.
E.g. XrCompositionLayerProjection contains pointers to potentially multiple XrCompositionLayerProjectionViews which contain a XrSwapchainSubImage which contains a swapchain.
I haven't checked if there are structs other than the composition layers that are affected by this.

The validity requirement is generated here but it only seems to check handles that are directly in the struct.
