[stable] [android] release background image readers on <= Android 14 (#171737)

CP of https://github.com/flutter/flutter/pull/171193. 

Template:

- Impacted Users (Approximately who will hit this issue, ex. all Flutter devs, Windows developers, all end-customers, apps using X framework feature).

All end users on Android 10-13 (inclusive) using an app with platform views.

- Impact Description (What is the impact? ex. visual jank on Samsung phones, app crash, cannot ship an iOS app. Does it impact development? ex. flutter doctor crashes when Android Studio is installed. Or shipping a production app? ex. the app crashes on launch).

Full app crash when backgrounding and then bringing the app back up.

- Workaround (Is there a workaround for this issue?)

No workaround.

- Risk (What is the risk level of this cherry-pick?)

Medium

- Test Coverage (Are you confident that your fix is well-tested by automated tests?)

No

- Validation Steps (What are the steps to validate that this fix works?)

Launch an app with platform views on these api levels and background them, and then bring the app back up.
