This is a cleanup follow-up, removing `FontFileWriter.FontTracker` and all
related uses. `FontTracker` was tracking font size use when SecurityManager was
present, however since we removed SM, `FontTracker` was no longer activated and
as such was dead code.
`FontFileWriter.FontTracker` and its use in `FontFileWriter` + related methods
were removed. This in turn cleaned up `PrismFontFile` and made a couple of
variables not longer used, including a `bool tracking` argument in constructor.
These cleanups propagated to `PrismFontFactory`, `{CT,DW,FT}Factory` and
`{CT,DW,FT}FontFile` classes.
Tests worked the same after this change.
