RFR: 8365625: Can't change accelerator colors in Windows L&F

[Alexey Ivanov]

**Problem:**

The colors for the accelerators are cached in static fields: `disabledForeground`, `acceleratorSelectionForeground` and `acceleratorForeground`. As soon as this field is set to a non-`UIResource` value, the value cannot change.

**Fix:**

Remove the static fields for accelerator from `WindowsMenuItemUI` and use the fields inherited from `BasicMenuItemUI`, pass these fields as parameters to static methods.

Additionally, I formatted the calls to `WindowsMenuItemUI.paintMenuItem` in one consistent way.

I removed the redundant javadoc from `paintMenuItem` and added the missing `@Override` annotation.

I provided a regression test. The test also reproduces [JDK-8365375](https://bugs.openjdk.org/browse/JDK-8365375) that was resolved in #26743.
