Editors: fix placeholder text alignment

The internal QQuickPlaceholderText creates an "implicit binding"
to the editor's horizontalAlignment, meaning that the placeholder
respects the editor's horizontal alignment when explicitly set,
and otherwise determines the alignment from the placeholder text's
visual direction.

[ChangeLog][Controls][TextField] Fixed the horizontal alignment
of the placeholder text in right-to-left UIs.

[ChangeLog][Controls][TextArea] Fixed the horizontal alignment
