Fix T86796: moving the cursor in the UV Editor does not take aspect into
account

UV coords are scaled by aspects (see UVsToTransData). This also applies
for the Cursor in the UV Editor which also means that for display and
when the cursor coords are flushed (new 'recalcData_cursor_image' was
added for this), these need to be converted each time.
