LibGfx+Userland: Move FontWeight enum into its own file

FontDatabase.h with its includes add up to quite a lot of code. In the
next commit, compiled GML files are going to need to access the
FontWeight enum, so let's allow them to do that without pulling in lots
of other things.

Also, change users to include FontWeight.h instead of FontDatabase.h
where appropriate.
