AX: Decrease size of TextMarkerData and AXIsolatedTree with better member
variable ordering
https://bugs.webkit.org/show_bug.cgi?id=294690
rdar://153759692
Reviewed by Joshua Hoffman.
Re-order member variables to move small fields into space that would otherwise
be wasted by padding.
TextMarkerData (and thus AXTextMarker) size is decreased from 32 bytes to 28
bytes, in turn decreasing the size of
AXTextMarkerRange from 64 bytes to 56 bytes.
AXIsolatedTree size is decreased from 624 bytes to 576 bytes.
