[psaux] Performance improvements (#43248). 

Implement proper disabling of hinting procedures when not hinting. This
results in a ~30% speedup.

* src/psaux/pshints.h (CF2_HintData): Gather hintmaps into hinting context.
* src/psaux/pshints.c: Do not allocate structs unless needed.
Skip hintmap funcs calls.
Update references.

* src/psaux/psintrp.c (cf2_interpT2CharString): Initialization for hinting
context.
<cntrmask, hintmask>: Ignore if not hinting.
Update references.
