clean_type3_font decoded and parsed every surviving glyph program of a
font, for every font. Many small font dictionaries sharing one
compressed CharProc multiplied that work without multiplying the stored
data, with a fresh allowance for each decode.
The resource names each indirect glyph program uses are now cached by
object across fonts (resource-name interpretation stays per font, since
each font prunes its own /Resources), and all decoding spends one
cleanup-wide DecodeBudget; past it the cleanup fails closed.
