Installer modules: add a "helper" file tag to pull in dependent inputs

Use case: building an Inno Setup, NSIS, or WiX project often depends on
artifacts created by other products (executables, shared libraries,
etc.). This allows the rules which create these installer files to
depend on relevant installable artifacts.

[ChangeLog] The Inno Setup, NSIS, and WiX modules' rules now have a
dependency on installable artifacts of dependencies by default, via
the default item templates InnoSetup, NSISSetup,
and WindowsInstallerPackage. This can be explicitly controlled via the
dependsOnInstallables boolean property of those item templates.
