Subject: Proof_global: pass only 1 pstate when we don't want the proof stack

Typically instead of [start_proof : ontop:Proof_global.t option -> bla ->
Proof_global.t] we have [start_proof : bla -> Proof_global.pstate] and
the pstate is pushed on the stack by a caller around the
vernacentries/mlg level.

Naming can be a bit awkward, hopefully it can be improved (maybe in a
followup PR).

We can see some patterns appear waiting for nicer combinators, eg in
mlg we often only want to work with the current proof, not the stack.

Behaviour should be similar modulo bugs, let's see what CI says.
