This is a follow up PR for #7166 adds @objc annotations to Swift catalogMetadata() methods, because the Swift 4 compiler no longer attempts to infer what methods should be visible to Objective-C. As a result of this change in the compiler, no Swift examples were showing up in Dragons after #7166. See this article: https://useyourloaf.com/blog/objc-warnings-upgrading-to-swift-4/ for additional context.
### Context
A client is wanting to animate the corner radius of a view that has a `MDCShadowLayer` backing layer. This currently doesn't render correctly. The work done in #5398 still does not support animating the corner radius. #5398 additionally doesn't animate the `shadowPath` property so it still won't work properly. We set the properties in the `CATransaction completionBlock` because this prevents the layer from snapping back to it's original state after the animation completes. If a client desires to use a `CATransaction` wrapper around this animation they can do so as outlined [here](https://developer.apple.com/documentation/quartzcore/catransaction).
### The problem
Animating corner radius changes in a CAAnimation don't render
### The fix
Add an API to allow clients to animate corner radius changes for MDCShadowLayer.
### Alternatives
1. Alternatives to adding a new API would be to have the a client use our private API which isn't desirable and not future proof as discussed in #5566.
2. Add an API `- (CAGroupAnimation *)animateCornerRadius:(CGFloat)cornerRadius;` that would return all 5 of the animations and clients could set the duration and timingFunction themselves but this doesn't allow for the layers to stay animated after completion. If we want the layer to be animated after completion we could use `kCAFillModeForwards` and `removeOnCompletion = NO` but that would prevent use from animating back to the original state.

### Bugs remaining
1. Set the MDShadowLayer cornerRadius to 0.
2. Call the new API with a duration of 5 seconds and a cornerRadius of 10.
3. Before that animation completes call the API again with a cornerRadius of 0.
#### Expected behavior
The first animation would complete and then the second animation would start.
#### Actual behavior
The animation jumps to 10 and then animates back to 0.
**_note_** This could be avoided if we added a property `BOOL` called `_isAnimating` and if that is set to `YES` then we would stash the next animation. This isn't added because most animations will be too fast for a user to tap that fast.
### Tested
cl/219964460
Removes the need to copy-paste stanzas from other files anymore as we'll rely on #4478 to generate the correct stanza for us instead.

* [Collections] Modernize Swift in styling readme.
* [ShadowElevations] Update ShadowElevations to be extensible.
This defines a custom macro to get the typed enum behavior rather than
defining a system macro to prevent it from adversily affecting clients.
Redundant NS_SWIFT_NAME macros are removed.
Usage is updated to omit the optional rawValue: argument. Docs are also
updated to reflect the change.
* minor fixes
* need an extra clause for xcode8
* updated for xcode8 backwards compat
All examples now have at least the required `+catalogBreadcrumbs` and `+catalogIsPrimaryDemo`. All examples in the same breadcrumbs path have only one primary demo. There should be only one `-catalogDescription` attached to the primary demo.
Closes#1897
* ClangFormat changes.
* Added swiftlint to scripts/format_all.`
* Fix scripts/lint_all to work from any directory.

* Remove the checks for force casting (! operator).
* Some fixes.
* More Swift fixes.
* Integrate SwiftLint in the Catalog.
* Update the disabled SwiftLint rules.
* Reference a local swiftlint.yml symlink.
This prevents us from getting warnings about code style violations from the other demos.
* Fix SwiftLint violations in the Catalog and Components.
* Ignore the `third_party` directory when running the linter.
We should not have to deal with warnings in code we may not be able to fix easily.
* Integrate SwiftLint into Shrine.
Additionally, fix a number of warnings introduced.

* Enable many of the previously disabled rules and correct them.
* Fix control statement violations from SwiftLint.
