Android: Fix version mapping from sdk_definitions.json

- Support multi-digit values for version ranges, via "+" in the RegExp
- Turn the RegExp expression into a raw string for easier reading
- Fix shortVersion (Maj.Min.-1) handling by appending the ".-1"
- Explicitly define the Patch number range for 5.15 in sdk_definitions
