Update Makefile to use modern iteration
The current Makefile uses some vendor-specific method of looping over the SIZES variable.
This updates it to use normal Makefile pattern substitution design which is more universally compatible and also can be run fully in parallel.
I also modified the PSF and OTF generation to integrate appropriate size filters with comments explaining why.
While some other OS platforms support the 32x64 font size that is not supported by the Linux kernel as it has a hard limit on console fonts of 32x32 due to internal implementation details.
There seems to be issues with spaces vs TAB preventing this to work out of the box but even with it fixed it doesn't seem to work when I tested with both BSD Make and GNU Make.
What platform did you test your changes on?
