Add Support for Parsing Pass Names in the `InstrumentationPMDriver`

[matinraayai]

@Iasonaskrpr to be able to test an instrumentation pass we need to add logic for it to:

• Accept a list of pass names as a command line argument.
• If the list of pass names is not empty, it parses them and constructs an instrumentation pass pipeline.

Some challenges that I can think of:

• You need to distinguish between IR and MIR passes when parsing the names, because they have separate PMs. I think the best way to get around it to have two separate CLI arguments, one deal with IR pass names and the other deals with MIR pass names.
• Although you won't need it right now, we also need a way to read in serialized LLVM IR/MIR Module and MMI. We can discuss this further as you add the pipeline parsing.

I will do this as soon as I am done with the branch relaxation pass to be able to test it.
