Move WixVersion to new WixToolset.Versioning package in libs segment

WixVersion is already used by the Core toolset but could also be
useful for bootstrapper applications parsing bundle versions. The
WixToolset.Data assembly contains a significant amount of data that
bloats its size that bootstrapper applications would never need.
Extracting WixVersion to its own assembly makes it much more
useable.
