This updates the Flutter minimum iOS version from 12.0 to 13.0, adds a migrator for existing apps, and updates our own examples, tests, and benchmark apps to 13.0. A follow-up patch will drop iOS 13 `@available` checks in the embedder. This is required in order to use Swift in the embedder and not need to bundle the Swift runtime libs in every app that uses Flutter. Swift stable ABI As of March 2025, usage of iOS is well below 1%, see example public usage data here: https://telemetrydeck.com/survey/apple/iOS/majorSystemVersions/ This patch makes the following changes: 1. Updates ios_deployment_target from 12.0 to 13.0. 2. Changes templates to `IPHONEOS_DEPLOYMENT_TARGET`, `MinimumOSVersion`, and Podfile `platform :ios` to 12.0. 3. Adds migrator for Podfile part to migrate `platform :ios, '11.0'` -> `platform :ios, '12.0'` 4. Compiles with `-miphoneos-version-min=12.0` 5. Runs the migrator on all example apps and integration tests. 6. Updates examples, tests to iOS 13 deployment target It also updates `verify_exported.dart`: * iOS 13 introduces stricter separation of const and non-const global symbols. Previously, these were declared in the Mach-O `__DATA` section which may be mapped read-write, but now they're in a dedicated `__DATA_CONST` section which is mapped read-only. This adds `(__DATA_CONST,__const)` to the allowlist with the same enforcement on exported symbol naming as before.
