We may hide system titlebar by default at least on some well tested and recent enough platforms (Gnome derivates and Gtk+ > 3.20).
This patch implements -moz-gtk-csd-hide-titlebar-by-default media query
to check if the system titlebar should be disabled by default on Linux systems
(it's already disabled on Window/Mac).

It also removes explicit definition of browser.tabs.drawInTitlebar preference on Linux.
When browser.tabs.drawInTitlebar is missing the -moz-gtk-csd-hide-titlebar-by-default
is used to obtain the titlebar state. When browser.tabs.drawInTitlebar is set
in about:config or by Customize menu, the user peference is used instead of the default.

It also fixes a -moz-gtk-csd-available media query,
it was always true regardless the actual system setting.

Release Note Request (optional, but appreciated)
[Why is this notable]: User facing change
[Affects Firefox for Android]: No, Linux only
[Suggested wording]: System titlebar is hidden by default to match Gnome guideline (I invented the last one)

I went with this wording for Nightly notes:
On Linux the Title Bar is now merged with the Tab Bar by default. This new behavior can be modified via the Customize… item in the main menu.

After this change, whenever I start Firefox, the right-click dropdown menu and the autoscroll wheel appear about a titlebar's height below and to the right of the cursor position. It corrects itself once resize the window.

Bug 1521175 describes a regression from this change.

Bug 1529713 needs to be backported to FF66 or this bug should be reverted for FF66 due to regressions listed here.
