Specify release flag to build on newer JDKs

* Add maven.compiler.release option to force correct cross-compilation
  to Java 11 when building with a JDK newer than 11, such as JDK 17
* Remove unnecessary java source, target, and encoding config from
  plugins when those are already specified by properties
* Fix submodule for core/in-memory-accumulo to point to
  in-memory-accumulo's main branch instead of the one being developed
  for the accumulo4 branch
* Also fix the license name for Apache-2.0 (the recommended name is the
  SPDX name) and drop .txt from the license URL
