stransky e8f95a5a4c Bug 1880323 [Linux] Don't destroy layer manager at DisableRendering() r=emilio
Right now we destroy layer managed when nsWindow becomes hidden.
It makes sure that window rendering queue is suspended and invalid wl_surface is not used any more.
But it's also expensive operation and we need to create layer manager again if the window becomes visible again.
It also introduces a regression it tab is reparented and remairing nsWindow is closed.
In such case rendering pipeline is deleted and reparented tab is empty as associated rendering resources are already freed.

In this patch we don't delete layer manager on window hide but rather keep that operation to nsWindow::Destroy() as we do before.
Instead force GL backend to create small fallback EGLSurface for hidden nsWindow and keep potential async rendering running
until the window is deleted.

/*
* MozContainerWayland is a wrapper over MozContainer which provides
* wl_surface for MozContainer widget.
*
* The widget scheme looks like:
*
* ---------------------------------------------------------
* | mShell Gtk widget (contains wl_surface owned by Gtk+) |
* | |
* | --------------------------------------------------- |
* | | mContainer (contains wl_surface owned by Gtk+) | |
* | | | |
* | | --------------------------------------------- | |
* | | | wl_subsurface (attached to wl_surface | | |
* | | | of mContainer) | | |
* | | | | | |
* | | | | | |
* | | --------------------------------------------- | |
* | --------------------------------------------------- |
* ---------------------------------------------------------
*
* We draw to wl_subsurface owned by MozContainerWayland.
* We need to wait until wl_surface of mContainer is created
* and then we create and attach our wl_subsurface to it.
*
* First wl_subsurface creation has these steps:
*
* 1) moz_container_wayland_size_allocate() handler is called when
* mContainer size/position is known.
* It calls moz_container_wayland_surface_create_locked(), registers
* a frame callback handler
* moz_container_wayland_frame_callback_handler().
*
* 2) moz_container_wayland_frame_callback_handler() is called
* when wl_surface owned by mozContainer is ready.
* We call initial_draw_cbs() handler and we can create our wl_subsurface
* on top of wl_surface owned by mozContainer.
*
* When MozContainer hides/show again, moz_container_wayland_size_allocate()
* handler may not be called as MozContainer size is set. So after first
* show/hide sequence use moz_container_wayland_map_event() to create
* wl_subsurface of MozContainer.
