Subject: [PATCH] decouple compileSdk version from build tools version (#21205)

Summary:
Android CI was failing due to that it was trying to extract major version from build tools and use it to compile ReactAndroid. Now, it'll extract compileSdkVersion from ReactAndroid/build.gradle and use it.

Issue was that https://github.com/facebook/react-native/commit/68c7999c25efbc6fabf67e4130ac086c401b88e0 dowgraded compileSdk version to 26 while retaining build tools version as 27.0.3, so CI was trying to use SDK 27.
