Add many more global analyses. (#47875) 
* Update packages.

* Add many more global analyses.

* Catch trailing spaces and trailing newlines in all text files.
  Before we were only checking newly added files, but that means we
  missed some.

* Port the trailing spaces logic to work on Windows too.

* Correct all the files with trailing spaces and newlines.

* Refactor some of the dev/bots logic into a utils.dart library.
  Notably, the "exit" and "print" shims for testing are now usable
  from test.dart, analyze.dart, and run_command.dart.

* Add an "exitWithError" function that prints the red lines and
  then exits. This is the preferred way to exit from test.dart,
  analyze.dart, and run_command.dart.

* More consistency in the output of analyze.dart.

* Refactor analyze.dart to use the _allFiles file enumerating logic
  more widely.

* Add some double-checking logic to the _allFiles logic to catch
  cases where changes to that logic end up catching fewer files
  than expected (helps prevent future false positives).

* Add a check to prevent new binary files from being added to
  the repository. Grandfather in the binaries that we've already
  added.

* Update all the dependencies (needed because we now import crypto in
  dev/bots/analyze.dart).

Summary

This tests contains an app with a main page and sub pages. The main page contains a list of buttons; each button leads to a designated sub page when tapped on. Each sub page should displays some simple UIs to screenshot tested.

The flutter driver test runs the app and opens each page to take a screenshot. Then it compares the screenshot against a golden image stored in test_driver/goldens/<some_test_page_name>/<device_model>.png.

Add a new page to test

  1. Create a new class which extends Page and implement the UI to be tested in the build method.
  2. The new class should set a static title and key
  3. Add an instance of the new class to the _allPages list in the main.dart
  4. Create a new test case similar to "'A page with an image screenshot" in test_driver/main_test.dart to run the screenshot test.
  5. Create directories for the test: test_driver/goldens/<some_test_page_name> should be created before running the test based on the target platform the test is designed to run.

An example of a Page subclass can be found in lib/image_page.dart

Experiments

The test currently only runs on device lab ["mac/ios"] which runs the app on iPhone 6s.
