Fix incorrect handling of xrCreateSwapchainAndroidSurfaceKHR in template_gen_dispatch.cpp

[quic-yli25]

There is a bug in template_gen_dispatch.cpp that causes an error when destroying swapchain created by xrCreateSwapchainAndroidSurfaceKHR.

Here is an example. On Quest3, xrCreateSwapchainAndroidSurfaceKHR returns XR_SUCCESS, but xrDestroySwapchain returns XR_ERROR_HANDLE_INVALID.

CHECK(xrCreateSwapchainAndroidSurfaceKHR(session, &createInfo, &swapchain, &surface) == XR_SUCCESS);
CHECK(xrDestroySwapchain(swapchain) == XR_SUCCESS);

Check the log, there is an error message from conformance layer.

XrApiLayer_runtime_conformance: ERROR: Conformance Layer: Unknown handle used, created by unrecognized API call? Message = Encountered unknown XR_OBJECT_TYPE_SWAPCHAIN handle with value 519582891248
OpenXR_Conformance:   CHECK( xrDestroySwapchain(swapchain) == XR_SUCCESS )
OpenXR_Conformance: with expansion:
OpenXR_Conformance:   XR_ERROR_HANDLE_INVALID == XR_SUCCESS

template_gen_dispatch.cpp identifies a command as a create command if the function name includes "xrCreate" and the last parameter is a handle. xrCreateSwapchainAndroidSurfaceKHR is a special case because this is a create command but returned swapchain is not the last parameter. So template_gen_dispatch.cpp doesn't handle this command correctly.

Modify template_gen_dispatch.cpp, register handle state for swapchain created by xrCreateSwapchainAndroidSurfaceKHR.
