* feat: add CPython 3.15 support for iOS and Android

Add cp315 identifiers to build-platforms.toml for both iOS (arm64_iphoneos,
x86_64_iphonesimulator, arm64_iphonesimulator) and Android (arm64_v8a, x86_64).
Update bin/update_pythons.py to route iOS 3.15+ to python.org instead of
BeeWare GitHub releases. Update README.md platform table to show Android and
iOS as supported for 3.15. Add cp315-cp315 to expected_wheels test defaults
for android and ios platforms.

* fix: adjust expectations

All changes made and linting passes. Here's a summary of what was done:
1. test/utils.py:390-394 — Added "cp315-cp315": 24 to the Android API level mapping, fixing the KeyError: 'cp315-cp315' in test_android.py::test_expected_wheels.
2. cibuildwheel/resources/build-platforms.toml:247 — Removed the cp315-ios_x86_64_iphonesimulator entry since CPython 3.15 dropped Intel iOS simulator support.
3. test/utils.py:397-405 — Updated the iOS expected wheels logic to return an empty platform_tags list for x86_64 when the Python version is 3.15+, so no x86_64_iphonesimulator wheels are expected for cp315+ on Intel Macs.
The XCframework slice name (ios-arm64_x86_64-simulator) stays the same in ios.py — I verified the 3.15 tarball still uses that name. The target_python.exists() iOS ARM64 failure on the feature branch is a separate issue (the 3.15 python.org distribution has a different structure than the beeware distributions used for 3.13/3.14) — left alone per your request.

* feat: add CPython 3.15 support for Android only

Cherry-picked all changes from henryiii/feat/cp315-ios-android, then
reverted iOS-specific parts (iOS 3.15 build configs, ios.py assert
removal, update_pythons.py iOS URL logic, iOS test expectations, and
README iOS column for 3.15). Android cp315 entries, test expectations,
and README Android column remain.
