Remove vestigial references to deprecated jQuery dropdown in Repository -> Compare
What does this MR do?
Some references to a deprecated jQuery dropdown library remained in the "Repository -> Compare" page entrypoint despite it no longer having any effect.
This MR removes those references, removes the unneeded webpack entrypoint altogether, and colocates the dropdown initialization code with the one remaining entrypoint where it is actually utilized.
I have tested the "Repository -> Compare" page both with and without the :compare_repo_dropdown feature flag (#322141 (closed)) and this change has no effect on its behavior in either scenario.
