fix[venom]: stack reorder rework

[HodanPlodky]

What I did

Fixed the issue that was manifested in the snekmate test. This bug is reported in #4215

How I did it

The bug was caused by error in stack_reorder function. The function depends on the order of each operand but since the order changes there is the possibility to move same stack operand twice. To fix this issue I kept the information where necessary operands on stack.

How to verify it

The example from the issue does compile now.

i think the positions[stack.peek(final_stack_depth)] can be factored out into a variable
