[MSVIDC32] Keep using CRAM_MAGIC for info structure validation (#6498)

Browse source 
CRAM_MAGIC is being used to validate the info context structure contents
when the driver routines are being called, so partially revert 8be912147.

Just report "MSVC" as the main FourCC handler in CRAM_GetInfo() instead.
