* Update NDK build rule version
* Fix NDK API level check: I used `min` and `max` values in `platforms.json` as it is proper way to determine compatibility. However, it must be noted that some android targets (such as `benchmark_tool`) cannot be built even if the API level is greater than the one NDK supports, as they may need higher API versions (`gpu` delegate requires `>=26`).
