This patch does the following.
- Removes the return value, because none of the call sites check it.
- Removes the empty implementations from several nsIWidget instances, because
they can use the nsBaseWidget one.
Specifically: OnDefaultButtonLoaded, AttachNativeKeyEvent, BeginMoveDrag,
BeginResizeDrag, GetAttention. These are all fallible functions whose result is
always checked.
The patch also moves some trivial function definitions from nsBaseWidget.cpp to
nsBaseWidget.h, and removes the android BeginResizeDrag() because it can
use the nsBaseWidget one.

Its return value is only checked in one low-value assertion.
The patch also does the following.
- Removes the Android and GTK overloadings of EnableDragDrop(), which are
identical to the nsBaseWidget one.
- Streamlines the Windows implementation: fixes the indentation and takes
advantage of infallible |new|.
The only implementation of SetSizeMode() that can fail is the nsCocoaWindow
one, on an Objective C exception, which is unlikely and can be swallowed.
This allows some nsGlobalWindow functions to become infallible as well.
They don't need to be NS_IMETHOD, but they should be MOZ_MUST_USE. Adding the
latter catches a few missing checks, which the patch adds.
The patch also gives PuppetWidget an InfallibleCreate() function, which makes
the infallibility of PuppetWidget creation clear.
This patch makes GetBounds(), GetScreenBounds() and GetClientBounds() more
obviously infallible, like existing functions such as GetNaturalBounds() and
GetClientSize(). This results in clearer behaviour in nsCocoaWindow.mm if
Objective C exceptions occur. Along the way, the patch removes some useless
failure checks for these functions.
The patch also removes the NS_IMETHOD from GetRestoredBounds and makes that
function MOZ_MUST_USE.
This patch removes dozens of ToUnknown/FromUnknown conversions and doesn't add
any new ones, which is nice. It also removes UntypedDevPixelsToCocoaPoints(),
which is no longer needed.
