Description
Tiled lacks a way to group objects without affecting their rendering order relative to other objects, since the object layer functions as both a way of grouping objects, as well as a way of layering them on top of each other.
This could be solved either by introducing another grouping method that doesn't affect rendering order, or by introducing a "z" property on the object layer that would be used to render objects relative to other layers, where layers with the same "z" value would get their objects merged.
Originally suggested by @hepari as part of #2082 (point 6).

Research direction
No files or tests are named. Start by tracing how object layers group objects and determine rendering order, then compare the proposed grouping and z-order approaches with existing layer behavior. Done means an agreed and implemented way to group objects without changing their rendering order relative to other layers.
