[SPARK-43850][BUILD][GRAPHX] Remove the import for
`scala.language.higherKinds` and delete the corresponding suppression rule
### What changes were proposed in this pull request?
`scala.language.higherKinds` is deprecated and no longer needs to be
imported explicitly in Scala 2.13, so this PR removes the imports for
scala.language.higherKinds and the corresponding compiler suppression rules.
### Why are the changes needed?
In SPARK-43849(https://github.com/apache/spark/pull/41356), I added
compiler suppression rules to allow `unused imports` checks to work with both
Scala 2.12 and Scala 2.13. As there is no longer a need to support Scala 2.12,
we can now clean them up.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Pass GitHub Actions
### Was this patch authored or co-authored using generative AI tooling?
No
Closes #43128 from LuciferYang/SPARK-43850.
