[CONSRV]: Improvements for console font support (part 2):

- Use the font functions from the concfg library (see r74462) to create a new console font & retrieve its metrics, inspired by the suggestions from Katayama Hirofumi MZ in CORE-12451 and CORE-13122;
- Use string-safe functions to copy the font names into the fixed-size buffers;
- Use explicit UNICODE calls to GetObject and CreateFontIndirect.
Related to CORE-13182.
