[Impeller] Reland: Remove Entity capture/AiksInspector. (#52932)

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.

This reverts commit 3513909. (#52680)
