### Context
Clients may want to set the corner radius of a UIView that they have overridden the layerClass on to use MDCShadowLayer. Currently if the shadow layer's corner radius changes those changes are not rendered (see Shadow Corner Radius example in MDCDragons). This has been attempted in [this PR](https://github.com/material-components/material-components-ios/pull/4921) and [this PR](https://github.com/material-components/material-components-ios/pull/5224) both had to be rolled back. This is a similar change to #4921 except this change does NOT mark `shadowPathIsInvalid` or call `setNeedsLayout`. This differs from #5224 in that it doesn't set the `shadowPath`'s for the sublayers or set `shadowPathIsInvalid`.
### The problem
Corner radius changes aren't rendered when using MDCShadowLayer.
### The fix
Set the corner radius on the layer and sublayers and update the mask for the sublayers.
### Additional notes
A global presubmit has been run and succeeded.
Internal CL to test: cl/216562497
### Alternatives
@andrewoverton Suggest
```objectivec
-(void)setCornerRadius:(CGFloat)cornerRadius {
[super setCornerRadius:cornerRadius];
[self layoutSublayers];
}
```

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.

* First pass animated shadows
* Make order of ZShadow demo views consistent
* Clean up MaterialShadowedView
* More cleanup
* Revert one example change
* Move everything in to MDCShadowLayer
* Revert MaterialShadowedView.m
* Only animate if the size change is animated
* Remove duplicate method
* Copy animation instance instead of copying each property

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
