8344914: OOME in several tests since JDK-6672644 - JComboBox still scrolling

[DamonGuy]

Backout for #20845. Removes additions to BasicScrollBarUI and removes the test JComboBoxScrollFocusTest. Original PR caused some tests to fail that indicate a memory leak.

Ran clientlibs job in CI, and all relevant tests pass (including the few tests that were failing from the original PR).
