Michael Weghorn 07f4fa7119 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. Pending MR: [1]
