(Test cross-imports) Don't cross-import test utils

Some test files import test utilities from other library's tests. This won't be possible once Material and Cupertino are moved to the flutter/packages repo.

For example:

https://github.com/flutter/flutter/blob/935b8f70305b2d82d76b2a15d568d973e2835895/packages/flutter/test/material/scaffold_test.dart#L15

Umbrella issue: https://github.com/flutter/flutter/issues/177028

### What to do about it
 * Move the util to flutter_test if:
   - it's used in many places.
   - it has a solid API that has been in use for awhile and we are ready to commit to it.
   - it's of public-level quality.
 * Duplicate the util if:
   - its implementation is trivial, or it's just a constant, etc.
   - we are worried about its API needing changes and don't want to make it public.
 * Any other options? I don't think it will be possible to import it any other way.

### The utils

Rendering:
 * [TestCallbackPainter](https://github.com/flutter/flutter/blob/0ef66c7d1a4c3ed303fdd2aa0349d39955b0e0ef/packages/flutter/test/rendering/rendering_tester.dart#L286)

Widgets:
 * [TestSemantics](https://github.com/flutter/flutter/blob/0ef66c7d1a4c3ed303fdd2aa0349d39955b0e0ef/packages/flutter/test/widgets/semantics_tester.dart#L22)
   - A very common one.
 * [TestListTile](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/list_tile_test_utils.dart)
 * [editable_text_utils](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/editable_text_utils.dart)
    - May contain several members that need to move. https://github.com/flutter/flutter/pull/182632 is moving TestTextField out of this file right now. I see lots of uses of textOffsetToPosition too.
   - textOffsetToPosition
 * [MockClipboard](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/clipboard_utils.dart)
 * [live_text_utils.dart](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/live_text_utils.dart)
 * [text_selection_toolbar_utils.dart](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/text_selection_toolbar_utils.dart)
 * [simullateSystemBack](https://github.com/flutter/flutter/blob/master/examples/api/test/widgets/navigator_utils.dart)
 * [FeedbackTester](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/feedback_tester.dart)
 * [MockProcessTextHandler](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/process_text_utils.dart)
 * [verifySliverGeometry](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/sliver_test_utils.dart)
 * [FakeView](https://github.com/flutter/flutter/blob/master/packages/flutter_test/test/multi_view_testing.dart)
 * [TestBorder](https://github.com/flutter/flutter/blob/master/packages/flutter/test/widgets/test_border.dart)
