This extracts a BaseMatrix template of which Matrix is now a particular
specialization. The BaseMatrix allows us to reuse the same code for
floats and doubles, much like the other "base" classes (BasePoint,
BaseRect, etc.).

The approach taken is to implement the metafunction by specialization as usual,
and then wrap it into an alias template. This avoids having to write "typename"
and "::Type" at the use site.

This requires adding a new overloading of LayoutDevicePixel::ToAppUnits and a
new PixelCastJustification: LayoutDeviceIsParentLayerForRCDRSF.

This patch converts Event::GetScreenCoords to return the same type as Event::GetClientCoords
and Event::GetPageCoords which is a CSSIntPoint. When the function was originally updated it
was switched to returning LayoutDevicePoint. Additionally the redundant functions
UIEvent::CalculateClientPoint and UIEvent::CalculateScreenPoint were removed.

The overloads return PointTyped, leaving it to the caller to round or truncate
if desired, much like the existing Rect counterparts.

This makes APZ behave nicely with most uses of a css transform:scale.
Summary of changes:
- FrameMetrics::mCumulativeResolution now includes the css-driven resolution
in addition to the pres-shell resolution.
- Displayports are now stored in Screen pixels rather than Layer pixels.
This is what we want anyways (as we'd like the displayport size to remain
constant as a fraction of the screen size), but it was necessary to make
this change as part of this patch because continuing to store them in
Layer pixels in the presence of a css-driven resolution would have
required a bunch of infrastructure to implement correctly.
Remaining work:
- Layout painting a scrollable layer at a resolution different from the
scale induced by the css transform causes problems. These will go away
with bug 1076192.
- Different resolutions on the x and y axes are not supported. This is
tracked by bug 1039967.
