Problem/Motivation
#2346019: Handle initial values when creating a new field storage definition added basic initial value support for single-valued base fields (i.e. stored in the shared tables). We should try to add this feature to multi-valued base fields and configurable fields as well, as proposed in #2346019-3: Handle initial values when creating a new field storage definition.
Proposed resolution
Investigate how we could implement initial values support for configurable and multi-valued fields.
