BaseTools: Add image type into generate map file

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2977

For a source-level BIOS debugger the .map files are quite useful with one
major shortcoming: the debugger cannot know, solely from the .map file,
the format (PE/COFF vs. TE) of the image included in the final BIOS ROM

Add Type=PE or TE in the map file
