VM Fix compound subassignment of globals (bug #64702)

Also fix some other places with the same potential problem.

* libinterp/parse-tree/pt-bytecode-vm.cc: Ref, deref properly
* test/compile/bytecode.tst: Update tests
* test/compile/bytecode_global_1.m

VM machine has issues with shorthand and assignment operators for global variables.
 
It throws an error
'error: can't perform indexing operations for global value reference type'.

Normal assignment does work without any issues.


script "test2.m"
------------------------------------------------

   global TT;

   sz = [5,1];
   TT = zeros(sz);
   idx = 1:3;
   TT (idx)  = TT (idx) + 5;
   disp(TT);

   printf("\n");
   TT (idx)  += 5;
   disp(TT);

--------------------------------------------------

_enable_vm_eval_ (0);
source test2.m
