refactor: create cost-insights-common isomorphic package

This moves most of the cost-insights API types into a separate isomorphic @backstage/plugin-cost-insights-common package. This will allow these types to be used by a a cost-insights backend or other product specific modules. Signed-off-by: Andrew Thauer <athauer@wealthsimple.com>

-  An entity is a tree-like structure that represents any unique
-  product or service that generates cost over a fixed period of time.
-  An entity could be atomic or composite. An atomic entity is indivisible
-  and cannot be broken into sub-entities.
-
-  A composite entity is divided into sub-entities that account for portions
-  of the total cost **over the same time period**. The root entity is
-  expected to only have _one_ Record consisting of the sub-entities to display
-  in the product panel (keyed by the entity type, such as "service" for
-  compute entities).
-
-  The root sub-entities may have multiple breakdowns  - for example, a
-  breakdown of an entity cost by SKU vs deployment environment. The sum
-  aggregated cost of each keyed breakdown should equal the sub-entity's cost.
-
-  Entities with null ids are considered "unlabeled" - costs without attribution.
-  If an entity is a composite, it may only have one (1) null child but may have any number of
-  null grandchildren.
