Build kotlin-reflect.jar in build.xml and for Maven

Reflection will be distributed in a separate jar and not in kotlin-runtime.jar
for two primary reasons:
- Reflection implementation at the moment takes almost 2Mb
- Separate libraries for separate features is a technique encouraged by Maven,
  and it's inconvenient to make it different in the compiler distribution
