- #7413 part 1 of 2
- made all `ModelMetadataProvider` and `ObjectModelValidator`-specific code conditional
- fortunately, `MvcOptions` easy to get; affected code is primarily `internal` or pub-`Internal`
- remove unnecessary `ModelMetadataProvider` use in `ApiBehaviorApplicationModelProvider`
- run integration and functional tests with `CompatibilityVersion.Version_2_1`
- functional test change depends on @javiercn's recent #7541 fix
- remove test code now redundantly turning compatibility switches on
nits:
- correct spelling errors in `CompatibilitySwitch`
- take VS suggestions, mostly in test code
- rename methods in `ControllerBinderDelegateProviderTest` to match current API
- slightly refactor in `ApiBehaviorApplicationModelProvider`
This issue causes problems with ValueTuple when used across assembly
boundaries between netstandard and net4X when net471 is installed. These
tests fail consistently in appveyor and will fail on any machine with
net471 installed.
