VS: Refactor target ordering logic

Refactor cmGlobalVisualStudioGenerator::TargetCompare to store the name of
the target that should come first instead of hard-coding "ALL_BUILD".
Update client sites to specify "ALL_BUILD" when ordering for .sln files
and an empty string otherwise (in cases when "ALL_BUILD" should not be
encountered anyway).
