Kapt: Replace original Javac diagnostic messages with those with Kotlin location mapped

There is no Messages dialog in newer versions of IDEA/Android Studio in which the error messages were mapped before. The new Build window shows only the original locations, so now we need to replace Java file diagnostics with ones mapped to Kotlin source files.

The side effect is that diagnostics on the same locations are automatically merged.
