split floor into floor_common, floor, floor_ffi to be able to use floor without flutter.

closes #637

• splits floor in floor_common, floor_ffi and floor.
• floor_common and floor_ffi do not depend on flutter or sqflite (only sqflite_common and sqflite_common_ffi)
• floor depends on flutter, sqflite and sqflite_common_ffi, re-exports all floor_common

thanks for implementing this improvement! i'll align our ci setup to these changes and eventually, i'll report back with suggested improvements.

Thanks for considering my MR!

I've been successfully using my branch in a small project in which I wanted to write a dart only CLI to use on desktop.

One small issue I see is the generated code depends on sqfliteDatabaseFactory which needs to be initialized differently if using floor (flutter) or floor_ffi (dart only). The implication is the code declaring the database has to import one or the other. As a result, the database class cannot be added to a common package imported by both a flutter app or a dart only cli app. This doesn't seem to be a big issue IMHO (an abstract base class gets most of the job done), but just something for you to be aware.

If you have any concerns, I'll be happy to update this MR. Or feel free to use my MR as you see fit in case you want to use it as a basis to do your own MR.

Thanks!

I see this PR checks in the generated code now. We did not have this before and they were git ignored, but only under /floor. Now that all this lives under floor_common, the gitignore must be updated. @hendrikvdkaaden Can you remove the generated files from git and after that update the gitignore file?
