Fix bugs in LogicStructure instrumentation calls to packed and changed issues across Simulator.reset

[mkorbel1]

Description & Motivation

This PR addresses two categories of issues:

• Non-synthesizable (instrumentation) calls to LogicStructures would call packed sometimes, which could result in non-functional generation impact and unexpected nulls in things like previousValue. Non-synthesizable APIs on LogicStructure rely on packed #457
• The changed mechanism in Logic did not work properly across Simulator.reset calls, so this PR also fixes these issues. This was discovered during fixes to the first bullet.
