Remove ur_base_desc_t, use ur_base_properties_t instead.

[aarongreig]

The definitions of these two base structs are slightly different which potentially has weird consequences if a given pNext chain contains extension structs derived from both. Unifying these structs removes the possibility of their definitions drifting further apart and prevents the mixed pNext chain scenario.

@jandres742 it looks like UR inherited this design from level zero, do you have any insight on why two base structs were used, and if there's a good reason to keep them for UR?

@aarongreig : I dont recall exactly, but I think original idea is that base_desc and base_properties could have other base fields added in the future, specific to descriptors and properties, besides pNext and stype. but as you mention.

I think change is good and would reduce code cluttering.

I don't have an opinion on the change as a whole, but the modifications to command-buffers are good.

[fabiomestre]

I have updated the target branch of this PR from the adapters branch to the main branch.
Development in UR is moving back to main. The adapters branch will soon be deleted.
