qt a11y: Implement QtAccessibleWidget::text{After,Before}Offset

In a quick test with a Writer paragraph having the text
"Abcd efgh ijkl" selected in Accerciser's treeview of the
LO a11y hierarchy, the results of running these
commands looked as expected:

In [28]: text = acc.queryText()
In [29]: text.getTextBeforeOffset(4, pyatspi.text.TEXT_BOUNDARY_CHAR)
Out[29]: ('d', 3, 4)
In [30]: text.getTextAfterOffset(4, pyatspi.text.TEXT_BOUNDARY_CHAR)
Out[30]: ('e', 5, 6)
In [31]: text.getTextBeforeOffset(4, pyatspi.text.TEXT_BOUNDARY_WORD_START)
Out[31]: ('Abcd', 0, 4)
In [32]: text.getTextAfterOffset(4, pyatspi.text.TEXT_BOUNDARY_WORD_START)
Out[32]: ('efgh', 5, 9)
