Gray Mackall 542d29dedd Upgrade Android SDK to 34 "UpsideDownCake" (flutter/engine#47609) 
~**This should not land until https://github.com/flutter/buildroot/pull/790 (re)lands, and I swap the buildroot url back to the latest commit.**~ ~Reland of PR to update buildroot at https://github.com/flutter/buildroot/pull/792. ~ <- landed, and changed the buildroot commit to the latest in DEPS

Upgrades to android api 34

Also:
1. Upgrades to java 17 in DEPS/ci, because the linter now requires it.
2. Stops running some roboelectric tests on android apis 16-18, because Roboelectric indicated those versions were unsupported and we don't support them either.
3. Applies the four trivial new suggestions from the newer linter.
4. Updates the baseline lint to include the new non-trivial lint ([fixed in a different PR](https://github.com/flutter/engine/pull/47817/files)).
5. Changes some instances where we were hardcoding android apis as numbers (e.g. `sdk = 16') to use version codes (see the [comment below](https://github.com/flutter/engine/pull/47609#issuecomment-1800308658)).

README.md

Unit testing Java code

All Java code in the engine should now be able to be tested with Robolectric 4.10.3 and JUnit 4. The test suite has been added after the bulk of the Java code was first written, so most of these classes do not have existing tests. Ideally code after this point should be tested, either with unit tests here or with integration tests in other repos.

Adding a new test

  1. Create a file under test/ matching the path and name of the class under test. For example, shell/platform/android/io/flutter/util/Preconditions.java -> shell/platform/android/**test**/io/flutter/util/Preconditions**Test**.java.
  2. Add your file to the sources of the robolectric_tests build target in /shell/platform/android/BUILD.gn. This compiles the test class into the test jar.
  3. Import your test class and add it to the @SuiteClasses annotation in FlutterTestSuite.java. This makes sure the test is actually executed at run time.
  4. Write your test.
  5. Build and run with testing/run_tests.py [--type=java] [--java-filter=<test_class_name>].

Note that testing/run_tests.py does not build the engine binaries; instead they should be built prior to running this command and also when the source files change. See Compiling the engine for details on how to do so.

Q&A

My new test won't run. There's a "ClassNotFoundException".

See Updating Embedding Dependencies.

My new test won't compile. It can't find one of my imports.
