[openimageio] Separate feature flags for tools and viewer (#34556) (#34699)
* [openimageio] Separate feature flags for tools and viewer (#34556)

Add feature flag "viewer" which controls building the viewer "iv".
Drop feature flag "tools", build tools (excluding the viewer) unconditionally.

* Re-add "tools" flag.
Make "viewer" flag depend on "tools" flag.

* Ensure that Qt does not get picked up by accident if the "viewer" flag is not
selected.
Make hidden dependency of theia on OpenImageIO::iv explicit.

* Fix syntax error in USE_QT option.

* Use ENABLE_IV instead of USE_QT.
Remove explicit setting of -DUSE_QT=OFF.
