Warn/error on incompatible Java/Scala version

Some combinations of versions of Java, Scala, and Daffodil are known to be incompatible. The plugin should error or have a prominent warning when this is the case.

Known/documented incompatibilities:

> // Compatible version sets include:
> // Java 8, 11, Scala 2.12.11 (exactly), Daffodil 3.0.0 (and below)
> // Java 8, 11, 17, Scala 2.12.15 (and above), Daffodil 3.1.0 (and above)
> // cannot be java 17 with daffodil 2.7.0 and scalaVersion 2.12.11.

Note that we should only error on known incompatibilities so we can still test with new versions, even if they are not yet known to be compatible. If we later determine new versions are incompatible then we can update the plugin.

No files or tests are named. Start by tracing where the plugin receives or evaluates Java, Scala, and Daffodil versions, then compare that path with the documented compatible and incompatible combinations in the issue. Done means known incompatibilities produce a prominent warning or error while unknown combinations remain allowed.
