QuantityFormatter: Take UnitAbbreviationsCache instance, Format with TQuantity (#1551)
- `QuantityFormatter`: introducing an `UnitAbbreviationsCache` instance and `Format`-ing using a generic `TQuantity` - `UnitsNetSetup`: introduced an instance property for the `UnitFormatter` - `IQuantity`: added the `UnitKey` property (implemented explicitly) - replaced the existing usages of the `QuantityFormatter` and marked the static `Format` overloads as `[Obsolete]` fixes #1447 --------- Co-authored-by: Andreas Gullberg Larsen <andreas.larsen84@gmail.com>
