## Context
Error occurs when testing using Bazel.

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.
We have had errors when generating the docs using jazzy specifically around components giving a fatal error around not finding imports when depending on other components. This is because each component for jazzy is isolated and on its own unless we provide the framework root. This caused our website generator to crash each time and fail to generate a new website.
This should resolve this problem.
QA=
Before the fix when running the website generator we got these errors:
```
/material-components-ios/components/BottomAppBar/src/MDCBottomAppBarView.h:17:9: fatal error: 'MaterialButtons.h' file not found

Now we no longer get fatal errors or crash when running the script.
This change was automatically generated by running a find replace of the following strings:
```
mdc_unit_test_suite(
mdc_unit_test_suite(
name = "unit_tests",
```
And then running buildifier to enforce style:
find . -name BUILD | xargs ~/buildifier
Kokoro's Bazel version has been increased from 0.11.0 to 0.20.0
As part of this change, the `.kokoro` bazel header rewrite phase's rewrites for MDF libraries has been made less generic because MDFInternationalization can now be imported using framework-style imports as expected. MDFTextAccessibility does not yet have this functionality, so we still need to rewrite it.
Version changes in the bazel workspace:
- bazelbuild/rules_apple has been increased from 0.3.0 to 0.9.0
- bazel_skylib has been increased from 0.2.0 to 0.6.0
- bazelbuild/rules_swift has been added at 0.4.0
- xctestrunner has been increased from 0.2.1 to 0.2.5
- material_internationalization_ios has been increased from v1.0.4 to v2.0.1
- material_text_accessibility_ios has been increased from fd570d71ae0124c75ad5af00e6b8b4b1668d5e40 to v2.0.0
- motion_interchange_objc has been increased from v1.6.0 to v2.0.0
- motion_animator_objc has been increased from v2.5.0 to v3.0.0
- motion_transitioning_objc has been increased from v5.0.0 to v6.0.0
- Swift version has been pinned to 3 for all swift libraries.
buildifier was ran on all affected build targets.
This unblocks https://github.com/material-components/material-components-ios/pull/5550.
This ensures that code will be built against the Swift version it was written in if/when the default Swift version changes.
This is an automated change generated by running:
buildozer 'add copts -swift-version 3' //...:%swift_library
buildozer can be downloaded and installed from https://github.com/bazelbuild/buildtools
This is an automated change generated by running the following command:
find . -name BUILD | xargs buildifier
buildifier can be installed from https://github.com/bazelbuild/buildtools
This change formats all of our BUILD files with the buildifier formatter in preparation for us having a BUILD format linter as part of our presubmits and so that we can cleanly run buildozer commands against the codebase.
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`.

Many of our Swift examples are either missing imports or are importing all of
MaterialComponents. Both of these will cause failures during internal builds.
* Updated known shortlink destination URLs to use short links.
* Updated stray links in the CHANGELOG.md.
* Fixed FAB shortlink.
* Applied replacements to everything outside of components/.
* Documented, clarified, and cleaned up warning flags.
* Fixed places where properties are missing `nonatomic`.
* Removed unused MDC_DEPRECATION_WARNINGS.
* Reviewer suggestions.
* Changed -Wshadow-all back to -Wshadow, since -Wshadow-all doesn't seem to be supported by Kokoro?
* Initial addition of kokoro and bazel continuous integration support.
Only adds support for ActivityIndicator and its dependencies. Will add other components to the continuous integration in follow up changes.
* Add AnimationTiming.
* Fix target name.
* Use ... matching to run all tests and build all targets.
* Just run tests.
* Add skeleton tests.
* Fix copyrights and build files.
* Add bzl file.
* Standardize build files.
* Fix typo.
* Naming.
* Remove confusing comment.
* Use Xcode 8.2.
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
* [Palette] Swift enums for MDCPaletteTint/Accent.
Note that this is a breaking change for Swift users. It changes
MDCPalette accent and names from stringly typed to strongly typed,
creating a new MDCPaletteTint and MDCPaletteAccent enum.
* Updated spacing
* update-unit-test
* Replacing methods with class properties.
* Updating docs to reflect new Swift call style.
* Updating examples.
* Updating ObjC examples to use dot syntax
* [Docs] Marks component files as API documentation roots.
Used by the site generator to determine where to build API docs. I
marked everything built by the previous version.
* [Docs] Adds a prefix to all Material guidelines links.
* [Docs] Adds API doc links to some components.
* [Docs] Changes an icon list class name.
* [Docs] Adds annotations to all installation code snippets.
* [Docs] Fixes screenshot sizes in PageControl README.
* [Docs] Fixes a broken link on the homepage.
* [Docs] Adds a stable repository branch field to the site metadata.
Used to link to the GitHub source tree.
* [Docs] Specify platform in docs root title.
