27134cda - Reduce Python reference cycles especially when interacting with MS Word (#11414)

Reduce Python reference cycles especially when interacting with MS Word (#11414) * Ensure XMLParser does not create reference cycles by not holding the internal parser at the same time as assigning our object's methods to it. * WordDocumentTextInfo: refactor the lazyControlField so that it is no longer inline and does not create a reference cycle. * EditableTextWithAutoSelectDetection: terminate automatic select detection in loseFocus event to ensure that NVDAObjects don't hold on to the TextInfo representing the selection for ever. * Fix linting issues * Address review comments
