Johannes Henkel f6a76fad93 [DevTools] Roll inspector protocol (Cleanup) (V8)
New revision: 4c2a3acaea9f2e7958081dd361f81e20e9eff5e7

This cleanup cl does not change any behavior, it just
cleans up some headers and does a class rename
(StreamingParserHandler->ParserHandler). It was reviewed
upstream
https://chromium-review.googlesource.com/c/deps/inspector_protocol/+/1924792
https://chromium-review.googlesource.com/c/deps/inspector_protocol/+/1925679
and does not touch V8 code. Would like to get
this in to make it easier to review subsequent changes.

Thanks!
