CL: migration functional test (#5560)

Closes: #XXX

## What is the purpose of the change

The following PR introduces a functional test that:
- Creates every type of balancer position that can be created
  - Bonded superfluid
  - Unbonded superfluid (locked)
  - Unbonded superfluid (unlocking)
  - Vanilla lock (locked)
  - Vanilla lock (unlocking)
  - No lock
- It then migrates each position, asserting invariants after each position is migrated
- Finally, an overall invariant is run after all positions have been migrated, asserting that all funds are accounted for in some way

The next PR subsequent to this will be adding randomization to the inputs in order to make the test non deterministic. 

## Testing and Verifying
