[CONCFG]: Diverse improvements/additions for the console configuration library. CORE-13182
- Use string-safe functions to copy the font names into the fixed-size buffers;
- Modify some default settings;
- Add a set of console font manipulation functions, to be used later by both the console applet console.cpl and by CONSRV.
  Some of these functions come from r74365 with minor improvements (see CORE-12451 too), others are based from a patch
  by Katayama Hirofumi MZ from CORE-13122, and the rest are needed for an upcoming commit for console.cpl.
- Add PCH support in concfg.
- Minor code formatting: Use our regular formatting for function prototypes.
