Bug 1826645 Part 2: Make Document hold fullscreen requests while an exit is being processed. r=edgar

This change makes the parent process delay a fullscreen request if there
is a pending fullscreen exit. It also changes the DOMFullscreenParent
actor listener lifecycle. Once it has started handling a fullscreen
request, it will remain a listener to the Document until it receives an
exit event when the manager is out of fullscreen.

This patch adds two new attributes to the window's `html` element, `windowclass` and `windowname`, to allow directly controlling the window's class hints on Xorg/Wayland (`res_class` and `res_name`) from the chrome/JS code. When they are set, values are used as class hints for their window. When they are not set, the current behavior of determining `res_class` and `res_name` (using `gdk_get_program_class` for `res_class` and parsing `windowtype` for `res_name`) is preserved.

Changes in `widget/nsIWidget.h` and `widget/nsBaseWidget.h` are only interface changes so that `setWindowClass` can accept three attributes. Although this patch does not affect Windows, `widget/windows/nsWindow.h` and `widget/windows/nsWindow.cpp` have been updated to comply with the new interface. `xpfe/appshell/AppWindow.cpp` has been updated to get the additional attributes and call `setWindowClass` with them. The main changes are in `widget/gtk/nsWindow.h` and `widget/gtk/nsWindow.cpp`.

Sync the chromemargin attribute to the widget before restoring the
sizes, since the later depend on the former.

This is the same order we use when sizing the shell in OnChromeLoaded,
so it should be more consistent.

Move it to the mozilla::widget namespace.

Use enum classes for transparency, popup type, popup level, etc.

Mostly automated with sed, but there were a few manual changes required
as well in windows code because they relied on Atomic<TransparencyMode>
working (which now doesn't because TransparencyMode is 1 byte instead of
4 bytes).

there are multiple request happens at a short time.

This patch tries to improve how we handle multiple request, we don't need to
track each request, but need to ensure widget matches with the latest fullscreen
state specified.
