Avoid weird scaling process for CFF

[dfrg]

See https://github.com/googlefonts/fontations/blob/756d45082d3832d0ec8bda6a30bc9b8bd1408424/skrifa/src/outline/cff/mod.rs#L444 where we apply a bunch of weird scale factors in discrete steps because FreeType does so. Note that FT applies these in different passes, in different locations in the code so it appears less chaotic but we don't have the same code structure.
