Update to Android 15

[nbradbury]

Fixes #21596

This PR updates WPAndroid & JPAndroid from SDK 14 to SDK 15, as has already been done for WCAndroid - p91TBi-cHS-p2. It will remain in draft until it has been completed and thoroughly tested.

Note that previously enableStrictMode was disabled, but I've re-enabled it for this PR so we could uncover detectNonSdkApiUsage violations. We should probably disable strict mode before merging this PR.
