tmf: Fix missing final sonarlint in TimeGraphEntry

Fix the SonarLint issue [1] below in TimeGraphEntry. Doing so happens to
fix a few more reported issues being consequences of [1].

Bump the necessary versioning, based on the Eclipse API build.

[1] Make this "public static WITHIN_COMPARATOR" field final.
