a11y: Send VALUE_CHANGED event for FormattedField
`VCLXAccessibleEdit::ProcessWindowEvent` takes care of sending a `TEXT_CHANGED` event. In the case of `SVTXAccessibleNumericField`, numeric values are handled, so send a `VALUE_CHANGED` event in addition. This makes Orca with the qt6 VCL plugin announce the new value when e.g. changing the page width using the arrow up key in the "Format" -> "Page Style" dialog. For Accerciser, an additional fix is needed so the value gets updated there in the interface view when the a11y object is selected.
