Rename "samples" segment to "tools"

This segment is a bit of a "miscellaneous section" in the WiX repo.
As such it has been difficult to name. I originally eschewed the
name "tools" because what is in the "wix" segment was once called
"tools". However, now that wix.exe is firmly established as the
entry point for WiX operations, I've become comfortable with its
segment being named "wix". That meant "tools" was again available
and "tools" better describes the content of this section.
