Updated tests in dev, examples/api, and tests/widgets to ensure that
they continue to pass when the default for `ThemeData.useMaterial3` is
changed to true.

Part of fixing #62833
This fixes (a bunch of) issues that have been reported differently over the years, but all have the same root cause. Sometimes the NestedScrollView would incorrectly calculate whether or not there is enough content to allow scrolling. This would only apply to drag scrolling (not mouse wheel scrolling for example). This did not relate to how the extent of the NestedScrollView is computed, but just the logic that enabled the actual drag gestures. This fixes that. :)
Fixes https://github.com/flutter/flutter/issues/126454.
In certain situations (see linked bug) the Scrollable needs access to the DPR of the View it is drawn into during disposal. Since inherited widget lookups are not allowed during disposal, we cannot look up the DPR dynamically in these situations. Instead, we have to cache the DPR when lookups are still allowed.
* Add clipBehavior to RenderFlex
* Add clipBehavior to FittedBox
* Add clipBehavior to Flex and FittedBox
* Add clipBehavior to UnconstrainedBox
* Add clipBehavior to Stack and Wrap
* Add clipBehavior to TextEditable
* Add clipBehavior to ListWheelScrollView
* Add clipBehavior to SingleChildScrollView
* Add clipBehavior to RenderViewportBase's widgets
Those widgets are NestedScrollView and ShrinkWrappingViewport.
* Fix tests
* Remove enum Overflow and fix typo
* Remove clipToSize
* Analyze fix
* Remove Mixin and other small fixes
* Fix tests and respect Stack's default clipBehavior
* Add Overflow back to make it non-breaking
* Restore clipBehavior to make it non-breaking
* Small fixes
* Fix rebase
* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
