8245634: [TestBug] Enable and fix tests ignored with message "impl_cssSet API removed"

[aghaisas]

This is a simple test fix.

Issue : https://bugs.openjdk.java.net/browse/JDK-8245634

After fixing JDK-8245457, I found that there are more ignored tests of similar nature that can be enabled and fixed.
A search for ignored tests with message "impl_cssSet API removed" - revealed a total 6 occurrences in 4 files -

1. CellTest
2. CheckBoxTest
3. ChoiceBoxTest
4. DateCellTest

This PR enables and fixes these tests.
