Remove unnecessarily set AdditionalLibraryDirectories

Some of these even pointed to directories that don't exist (and
don't get created during the build process).
Remove some manually set options, that are set to the default value

These are the only places where these options are overridden.
Don't set path to a precompiled header - precompiled headers are disabled
Set DebugInformationFormat consistently in all projects

Use the "Program Database (/Zi)" in release mode and in debug
mode for x64, use "Program Database for Edit & Continue (/ZI)"
in debug mode for Win32.

This is how new visual studio projects are set by default.
Don't set custom build options for VCMIDLTool

This tool isn't even used in the build (and thus, these settings
aren't even visible in the IDE).
