With this patch, 4-component MSI version can be used, e.g by setting
TINY_VERSION variable in CMake, or by adding a string, e.g
MYSQL_VERSION_EXTRA=-2
which sets TINY_VERSION to 2, and also changes the package name.

The 4-component MSI versions do not support MSI major upgrades, only minor
ones, i.e do not reinstall components, just update existing ones based
on versioning rules.

To support these rules, add DefaultVersion for the files that won't
otherwise be versioned - headers, static and import libraries,
pdbs, text - xml, python and perl scripts Also silence WiX warning
that MSI won't store hashes for those files anymore.
