Change WireBundle::Ctrl to WireBundle::TileControl. Decouple WireBundle and StrmSwPortType

[fifield]

This changes replaces the abbreviated WireBundle::Ctrl with WireBundle::TileControl and removes an implicit coupling between the WireBundle enum names and the aie-rt StrmSwPortType enum names.

Previously the xaie target (e.g. aie-translate --aie-generate-xaie) used the TableGen'd wireBundleStringify functions to emit StrmSwPortType enums directly as C++ source code. This PR replaces uses of wireBundleStringify in AIETargetXAIEV2 with a new utility function. This corrects a potential bug related to the PL port and allows the renaming of the control port.

While I'm normally very much in favor of avoiding abbreviations, I'm not 100% on board with this. The WireBundle names come from the architecture and at some point it's not good to have that inconsistency. But I guess there has to be some friction somewhere, the only question is where is the least confusing place for it to be?

As far as I know the Ctrl name comes from aie-rt StrmSwPortType enum. I see the port referred to as "tile_control" in the arch spec. Maybe that would be better?

I think it came from the AIE1 arch spec. TileControl indeed might be better? Given that it is itself inconsistent, I remove my objection :)

Updated to TileControl to be more....consistent.
