This disables the example from being ran during snapshot tests. The titles are not used in the catalog; the breadcrumbs are used instead to populate the title.

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.
Renaming each of the example view controllers to include
"ExampleViewController" so they're easier to find. This is closer to our
typical naming pattern for example view controllers.
Replacing all non-integral, single-precision floating point literals with double-precision values explicitly cast to CGFloat. For example, `0.1f` should become `(CGFloat)0.1`.
Regex used:
```
([0-9]*\.)([0-9]*?)([1-9]+)([0-9]*?)[fF]
```

### Context
When debugging Swift files through our Catalog and Dragons app, we were not able to see the variable values, or invoke a print `p` or print object `po` on variables successfully.
### The problem
There was a Swift class and an Objective-C class named exactly the same which was causing build errors when bridging both Swift and Objective-C in the MaterialComponentsExample module.
### The fix
Rename the Swift file to have a unique class name.
### Related Bugs

Closes#4240

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.

We can now make use of @available throughout our codebase.
We support Xcode 9 and up, which includes the iOS 11 SDK. This means we can remove any guards for SDKs prior to iOS 11.
This was cleaned up by running a global find-and-replace with the following regular expression:
```
Find:#if defined\(__IPHONE_11_0\) && \(__IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_11_0\)\n(.+if \(@available\(iOS 11.0, \*\)\) \{(?:.|\n)*?)(?:#else(?:.|\n)*?)?\n#endif
Replace:$1
```
With some additional cleanup for stragglers that didn't match this pattern. Note that else clauses were intentionally dropped.
Closes https://github.com/material-components/material-components-ios/issues/4909
Many of our Swift examples are either missing imports or are importing all of
MaterialComponents. Both of these will cause failures during internal builds.
Prior to iOS 11, UIKit will aggressively reset the top layout guide's value to a system default (usually of "20" if there's a status bar). This behavior was overriding our attempts to modify the top layout guide's constant such that it would include the flexible header's height.
Prior to this change - and only on pre-iOS 11 devices - the top layout guide was not being adjusted to include the flexible header's height. This meant that view controllers that relied on the top layout guide would lay out correctly on iOS 11 and above, but incorrectly on pre-iOS 11 devices.
This incorrect behavior can be seen in the AnimationTiming example. Note that the content is being positioned with the top layout guide in mind, but it is still behind the status bar.
After this change - and only on pre-iOS 11 devices - the flexible header will observe any changes made to the top layout guide constant and re-set the value to the calculated top layout guide inset. This ensures that the top layout guide adjustment behavior is consistent across our supported iOS versions. This was tested on an iOS 8.1 and iOS 10.3.1 simulator.
After this change, the AnimationTiming example correctly positions its content on pre-iOS 11 devices:
