[psaux] Add missing objects for Type 1. (1/2)

Move CF2_Font instance to PS_Decoder. This is the context for the interpreter
and since it is currently stored in CFF_Font, is unavailable in Type 1 mode.

* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): Add the
cf2_instance field.

* src/psaux/psdecode.c (ps_decoder_init): Copy cf2_instance to PS_Decoder.
Remove unused line.
* src/psaux/t1decode.c (t1_decoder_done): Add finalization code.

* src/psaux/psft.c: Update accesses.
