Update SkFont size documentation

The SkFont documentation currently claims that the size is in "points",
which is confusing since it isn't 1/72 of anything. Instead the size on
an SkFont is in the same units as any value passed to an SkCanvas, which
are documented as "local coordinate units". The value describes the size
to which the EM unit in the font must be scaled.
