Summary:
Run spm add with RN_STRICT_API=1 in the three SwiftPM CI jobs (RN-Tester, helloworld and the new-app flow), so the SwiftPM opt-in is exercised the way an app enables it. spm add records the choice in .spm-injected.json and defines RN_STRICT_API for the app target, the spm.modules packages (RN-Tester's sample native modules) and the app's codegen package.

This depends on the C++ stable API guards being textual header members of the prebuilt ReactNativeHeaders module map.

…droid C++ (react#59222)

Summary:

Two C++ files built into RN-Tester include public React Native headers directly instead of through their module umbrella, which is an `#error` under `RN_STRICT_API`:

- `rn-tester/NativeCxxModuleExample/NativeCxxModuleExample.cpp`,
- `react/debug/react_native_assert.h`,
- The checked-in codegen output of `react-native/popup-menu-android` (`Props.cpp`) included `react/renderer/core/PropsParserContext.h` and `propsConversions.h`.

No behavior change; this prepares RN-Tester to build with `RN_STRICT_API` by default.

Differential Revision: D126328619
Summary:

Turn on the C++ stable API checks (`RN_STRICT_API`) in RN-Tester by default, so the opt-ins and React Native's app-facing headers are exercised in strict mode on every build:

- Android: `strictCxxApiEnabled=true` in `android/app/gradle.properties`. 
- iOS (CocoaPods): the Podfile sets `RN_STRICT_API=1` unless the environment already sets it, so `pod install` applies it the same way an app would.

Summary:

Turn on the C++ stable API checks (`RN_STRICT_API`) in the template apps CI builds, so the opt-ins, React Native's app-facing headers and the generated codegen and autolinking code are compiled in strict mode the way a new app would build them:

- `private/helloworld`: `strictCxxApiEnabled=true` in `android/gradle.properties`, and the Podfile sets `RN_STRICT_API=1` unless the environment already sets it (`RN_STRICT_API=0 pod install` opts out). 
- Community template CI (cloned at build time): `build-android-templateapp.yml` appends `strictCxxApiEnabled=true` to the generated app's `gradle.properties`, and `e2e-ios-templateapp.yml` runs its `pod install` with `RN_STRICT_API=1`.

Summary:
Run `spm add` with `RN_STRICT_API=1` in the three SwiftPM CI jobs (RN-Tester, helloworld and the new-app flow), so the SwiftPM opt-in is exercised the way an app enables it. `spm add` records the choice in `.spm-injected.json` and defines `RN_STRICT_API` for the app target, the `spm.modules` packages (RN-Tester's sample native modules) and the app's codegen package.

This depends on the C++ stable API guards being `textual header` members of the prebuilt `ReactNativeHeaders` module map.
