QWidget/QLineEdit: deprecate get{Contents,Text}Margins()

We have contentsMargins() and textMargins() methods since 4.6 which
are much more efficient and easier to use.

[ChangeLog][QtWidgets][QLineEdit] The getTextMargins() member function
has been deprecated in favor of textMargins().

[ChangeLog][QtWidgets][QWidget] The getContentsMargins() member
function has been deprecated in favor of contentsMargins().
