SCons: Add `DEV_ENABLED` defines for `target=debug` builds

This will allow adding developer checks which will be fully compiled out in
user builds, unlike `DEBUG_ENABLED` which is included in debug tempates and
the editor builds.

This define is not used yet, but we'll soon add code that uses it, and change
some existing `DEBUG_ENABLED` checks to be performed only in dev builds.

Related to godotengine/godot-proposals#3371.
