Add Maven compiler problem matcher for javac diagnostics (#1086)

The javac problem matcher only recognized javac's native diagnostic
format (File.java:12: warning: msg), which works for plain javac and
Gradle but not Maven. The maven-compiler-plugin reformats diagnostics
to [WARNING] /path/File.java:[12,5] msg, so Maven builds produced zero
annotations.

Add a new maven-javac matcher owner that recognizes the Maven format,
capturing severity, file, line, column, and message. Maven builds now
annotate consistently with Gradle and plain javac.

Fixes: #1085

   * In `.sdkmanrc` file, java version should be preceded by the `java=` prefix (e.g., `java=17.0.7-tem`). When a recognized SDKMAN distribution suffix is present, setup-java can infer the `distribution` input automatically. Unrecognized suffixes require setting `distribution` explicitly. The `.sdkmanrc` file supports version specifications in accordance with [file format](https://sdkman.io/usage#env-command), see [Sdkman! documentation](https://sdkman.io/jdks) for more information.
