- #3227
- much of change is to tests, creating and passing `ModelMetadata`
- updated `InputFormatterContext` to make `ModelMetadata` available to `JsonInputFormatter`
- walk `ModelMetadata` tree to get information about property with an issue
- add missing `null` checks in `ModelStateDictionaryExtensions`
- #2722
- make communication of errors from formatters to `BodyModelBinder` explicit
- `JsonInputFormatter` now adds errors to `ModelStateDictionary` with correct key
- change `InputFormatter.SelectCharacterEncoding()` to add an error and return `null` when it fails
- one less `Exception` case and removes some duplicate code
nits:
- improve some doc comments (more `<inheritdoc/>`, `<paramref/>` and `<see/>`)
- add another two `BodyValidationIntegrationTests` tests
