Bug 1540581 - P6. Tidy some C++ declarations in gfx/. r=gerald,jrmuizel * Remove redundant virtual keywords * Mark all destructors of inheriting classes as virtual for clarity * Mark all classes without virtual destructor as final (exposed errors) * Make destructor virtual where it needed to be (some were missing) * Replace empty ({}) code declaration in header with = default * Remove virtual unused methods I probably missed some, it quickly became a rabbit hole. Differential Revision: https://phabricator.services.mozilla.com/D26060
