[Impeller] Remove Entity capture/AiksInspector. (#52526)

Resolves flutter/flutter#134748.

This was a really fun experiment. I learned a lot from it, and it genuinely helped me solve some coverage-related problems, but the reality is it was too little too late -- by the time we had this capture system, we had already solved most of the problems that would have benefitted from this.

It's been a few months since I've used or extended the capabilities of this capture system for something, and I don't have the spare time/energy to give it the love it needs to realize the vision I had for it. I still almost exclusively use a combination of native frame captures and print debugging to solve problems.

RIP in peace.
