Squashing all work to implement region-based OpenQASM3 modifier scope block

Descriptions: modifier (inv, ctrl, pow) Ops in the dialect has an associated (single-block) region. These ops have proper data flow tracking, i.e., subsequence quantum ops will take output of these modifier ops, not the wrapped instructions. The connection b/w the region-wrapped code and the op returns are handled by the quantum yield op (terminator for these modifier ops).

Lowering/optimization:

- If no optimization is required, these ops will be lowered to runtime (start/end) functions, identical to the current behavior. I need to separate part of this lowering (involves inlining the wrapped region into the parent region) to a individual pass, executed before the quantum-to-llvm dialect conversion b/c of some weird interactions with other dialect conversion patterns (e.g., qvs conversion) and type conversion. In some sense, when inlining the body, we are creating (cloning/copying) new MLIR Ops in the quantum dialect, so it needs to be executed before the whole quantum-to-llvm pass.

- If optimization is turned on: when possible (e.g., the wrapped code only contains qvs ops), it will resolve the modifier at compile time: reverse gates for inv, derive the ctr-gates, rewrite pow->for loops.

Modifiers that cannot be optimized will remain and  be handled by the lowering step above.

Added tests. There is an edge case that this doesn't cover is compute-action. I retain the existing behavior by directly calling runtime functions. Hence, the SSA tracking in this use case is not reliable for optimization.

Added <optional> header include

Required for gcc11+ due to header file re-structuring.

Fixed a bug in ScopedSymbolTable::invalidate_qubit_extracts

Must check the optional return before trying to deref.

This shows up in one of the demos whereby the QASM3 source only contains a kernel **definition** and the size of qreg argument is unknown.

Added HPC demo for random circuit (TNQVM) and adder circuit (DM-SIM )

To minimize the risk of Summit unavailability, TNQVM/ExaTN demo will be based on Andes.

DM-Sim on Summit: 1GPU demo on login node, multi-GPU live demo if interactive session available. Otherwise, just do a job submission...

The code to detect the type is correct in detecting Memref type or not but the below code **always** does a LoadOp.

In the case of non-memref type current value, it's causing seg-fault in LLVM internal code....

While having an LLVM build with assert on, fixing those asserts:

- extraneous eraseOp

- unused variable which is actually an error (cannot get Int/Float bit width of a memref type)

On Summit, looks like the Clang-CSP was not able to link properly at the final linking phase. So just having an option to use the system compiler if needed.
