Use DPI-aware borders

Reports usages of javax.swing.border.EmptyBorder and JBUI.Borders.emptyXyz() that can be simplified.

The EmptyBorder instances are not DPI-aware and can result in UI layout problems.

Quick fix performs replacement with JBUI.Borders.empty() or simplifies the expression.

Example:

// bad:
Border border1 = new EmptyBorder(1, 2, 3, 4);
Border border2 = new EmptyBorder(1, 2, 1, 2);
Border border3 = new EmptyBorder(1, 0, 0, 0);

// good:
Border border1 = JBUI.Borders.empty(1, 2, 3, 4);
Border border2 = JBUI.Borders.empty(1, 2);
Border border3 = JBUI.Borders.emptyTop(1);
