feature: ReflectionSource and DictionarySource (#426)

* Initial commit

* Make ReflectionSource.TypeCache static
* Control size of ReflectionSource.TypeCache, remove oldest item first
* dynamics in DictionarySource also use case-sensitivity setting
* Cache for IReadOnlyDictionary has instance scope

* Remove cache insertion tracker for NET6_0_OR_GREATER

Only before NETCore3.1, the dictionary is not ordered by insertion order.

* Add explicit EqualityComparer for creating the TypeCache dictionary

* Add comment about handling case-sensitivity
* Add test for: When there are multiple members with the same name but different case, the first member is used

* Add unit test for dynamics (ExpandoObject) case-insensitive

* refactor: Less cognitive complexity

* for DictionarySource
* for ReflectionSource

* chore: Fix indent
