parser: fix BSIM-BULK (level 77) model type lookup for OSDI MOSFETs 

inpdomod.c: Add case 77 to the MOS level switch so that .model lines
with level=77 resolve to the bsimbulk OSDI device type instead of
leaving INPmodType=-1.  Without this, BSIM-BULK model cards are
registered with an invalid type and instances later fail to load.

inp2m.c: Add bsimbulk to the model-type allowlist in INP2M() so that
MOSFET instances using an OSDI BSIM-BULK model (M-prefix) are accepted
instead of rejected with 'incorrect model type'.

This is the minimum subset needed for a single-model BSIM-BULK test
case to parse.  The multi-bin handling change to inpgmod.c that
accompanied the original fix is omitted here — it is unrelated to the
PMOS-polarity wiring demonstration this branch is for.
