Don't include version information in GeckoView project

We include Tor Browser version information when building the Firefox part, e.g. in order to get the (incremental) update files right (see: tor-browser-build#18326) or before accessing the profile has been loaded (see: tor-browser-build#18325).

But that should not be needed when building the GeckoView .aar as the application parts move to Fenix.

We should investigate and fix that as not needing to rebuild the whole GeckoView for Android could speed up our mobile releases a lot in case we need to get new ones out fast due to GeckoView unrelated reasons.
