Remove try/catch workaround in BreakpointLabelAction

The workaround in computeInlineEditorBounds() caught the
ArrayIndexOutOfBoundsException thrown by TreeItem.getBounds() on
macOS. That exception is fixed in SWT by
eclipse-platform/eclipse.platform.swt#3628
(included in I-builds from I20261007-2300 onwards), so the workaround
is no longer needed.

Follow-up to eclipse-platform/eclipse.platform.swt#2749
