tdf#152246 Fix RTL content control field position

With this patch, the horizonal position of the content control fields
are corrected. Previously, they were calculated just like the fields in
the LTR paragraphs. To implement this, I've used the
GetTextFrame()->SwitchLTRtoRTL method.

The remaining issue is that The exported fileds in the PDF are still LTR
themselves. For example, the combo box will still be LTR.

It should be pointed that handling vertical text is still an issue that
should be addressed later. If you rotate the paragraph with content
control field, the output does not obey, which is incorrect.
