[quick_actions] Adopt code-excerpts for README - #34

Work towards flutter/flutter#186906, flutter/flutter#191088

**Ports over flutter#11762 which landed on the `m3e_migration` feature branch.**

Since CI was not set up to run on that branch, I've pushed up a few more changes after the ported commits to get all the repo checks/tests to pass.

### Original PR description
Adds the initial gen_defaults sub-directory with the initial TokenTemplate and generator. This is simply the initial scaffold, we will need to add additional helper functions as necessary as we begin adding the actual templates.

### Original PR description

Work towards flutter/flutter#187899

Previously, the `gen_defaults` script generated the files in different directories based on whether or not the template was an M3 or M3E template. Since we are planning on using an variant enum instead of different libraries to separate M3 and M3E implementations, the `gen_defaults` script needs to be accordingly updated.

…tter#12618)

This converts CircleController, PolygonController, and PolylineController to Swift in the `_sdk*` packages.

The remaining Obj-C code will be migrated in a series of follow-up PRs to keep the scope of each PR reasonable for review.

The conversion process was:
- Initial conversion via Gemini, with explicit instruction to keep the structure the same.
- Side-by-side manual review of the old and new versions of the files.
- Manual fixes and improvements.

This includes test changes beyond what we would normally expect for a language conversion PR (e.g., name changes from dropping the prefix) because the conversion to Swift exposed a latent issue in the tests. Several tests had a pattern where a helper method was creating a local `mapView` instance, using it to construct the subcontroller under test, and then returning that subcontroller—at which point the map view goes out of scope. The subcontrollers have weak references to the map view, so it can be deallocated before the test actually runs, and doing so causes the tests to fail (as many operations in the subcontroller no-op when the map view is nil). In cases where the helper is only used once, it can be inlined; in cases where it's used repeatedly we can instead return multiple values and keep the map view alive.

Currently sync back pr for batch release is created as soon as the batch release PR merges.

This can be a problem if the release workflow runs on the release branch fails and someone accidentally merge the sync back pr without knowing. It will be extremely hard to clean up in this case.

The PR changes it that the sync back pr is only created when release finishes successfully.

After this change, if release fails, we can simply delete the release branch and re trigger the batch release workflow to try again.

Merging this PR carry a risk if there is bug in the new code in release_from_branch workflow. If you don't see a sync back pr the next time batch release, let me know and i can help clean up and fix.

If unconfigured or pointing to an unexpected path, it provides

This PR fixes the CupertinoIcons not being included in the actual examples and some leaks of TextEditingControllers,
which were things i noticed while fixing up cross imports (which by themselves have been fixed since then)

Since the Code Freeze period is still ongoing, I did not chance the version for cupertino_ui in the changelog yet.
