LibOverride: Massive edits to 'editable' IDs checks in editors code.

Add new `BKE_id_is_editable` helper in `BKE_lib_id.h`, that supercedes
previous check (simple `ID_IS_LINKED()` macro) for many editing cases.

This allows to also take into account 'system override' (aka
non-editable override) case.
