Test: fast/css-grid-layout/grid-template-get-set.html

Recognize, parse, store and return properly the value of
grid-template. It required some extra parsing code because the
specs mandates to check that the defined grid areas are indeed
rectangular. Named grid areas are still not fully supported, will
be done in a follow up patch.

As validating involves building the grid areas a new CSSValue was
added to hold the computed value. Note that we have to track the
explicit size of the named grid areas as the named grid areas
(".") are not tracked in our HashMap of grid areas.

This change also involves moving GridCoordinate and GridSpan to a
separate file in order to share the code that describes the grid
area coordinates.
