[MYDOCS] Add missing icons expected by 3rd party applications (#6576)

Add "My Documents" and "My Pictures" icons, with 100 and 101 identifiers
accordingly. They are duplicating the icons from shell32.

This fixes My Documents desktop icon becoming blank when reverting back
to the system default icons after applying 3rd party icon set in Stardock
IconPackager 5.1, and also fixes icons of some items in the application
preview dialog.

It's confirmed that mydocs.dll on Windows XP SP3 and Server 2003 SP2
includes these two icon resources with the said identifiers.
The icons there are being an exact copy from shell32 as well.
