Add Instruction Namer pass to PassManager

[tbennun]

This PR adds the built-in instruction namer pass to PassManager. The instnamer pass is very useful to work with the Python bindings, especially when value names are discarded during compilation and ValueRef.name is empty.

For some reason that is likely unrelated to the PR, rtd is failing to build

@tbennun indeed, it seems like there is an issue with a missing configuration file. I will investigate 🕵️

According to:

https://blog.readthedocs.com/migrate-configuration-v2/

I would say this is part of:

Monday, August 14, 2023: Do a second brownout (temporarily enforce this deprecation) for 24 hours: 00:01 PST to 23:59 PST (midnight)

So probably OK to just wait and restart the build tomorrow.

I will open a ticket that this must be resolved before 25 September.

RTD is building again

Can you add a test to exercise the pass?

[tbennun]

@sklam Added both to the populate passes test and to a specific behavior test

[sklam]

@tbennun, The test looks good and I have manually confirmed the behavior as well. One last thing, can you add docs for the new pass at docs/source/user-guide/binding/optimization-passes.rst? Thanks!

[tbennun]

@sklam of course! I don't know how I missed that. Added.

I've added this to the 0.42 milestone, such that it'll be considered for review.
