Simulate: Properly handle failing clear state programs

[jasonpaulos]

Problem

Currently the simulate endpoint does not properly handle failing clear state programs. Unlike every other type of program execution, if a clear state program rejects or errors, the transaction group continues and can still succeed. Any stateful operations the clear state program performed before it failed are rolled back.

Simulate incorrectly handled failing clear state programs in the following ways:

1. Reporting the wrong ApplyData for a failed clear state txn (it should be blank, but that's not what simulate reports)
2. If there's a later error, it uses the location of the earlier clear state error
3. For app state traces, it doesn't communicate that clear state operations should be rolled back

Solution

Implementation fixes for items 1 & 2 have been added in this PR.

Additionally, for item 3, the fields clear-state-rollback and clear-state-rollback-error have been added to the SimulationTransactionExecTrace object. If clear-state-rollback is true, this indicates to trace consumers that they must discard all state changes from the clear state trace after it finishes.

Test Plan

Unit tests added
