[android][coreclr] Make coreclr build specify HOST_ANDROID and include Android logging APIs (#112677)

- Define `HOST_ANDROID` for coreclr builds and link to Android logging APIs
- Make `jitprintf` use [Android logging APIs](https://developer.android.com/ndk/reference/group/logging) if printing to stdout
  - This allows us to get [JIT disassembly output](https://github.com/dotnet/runtime/blob/main/docs/design/coreclr/jit/viewing-jit-dumps.md#disassembly-output) via logcat
