I was working on porting performance-timeline WPT into core the other day and I realized that it didn't make sense to use the word whatwg in the file name (like what we do to other web-thingy) because performance-timeline is standardized in W3C but not in WHATWG. It sounds reasonable to me to change the whatwg in file names into web as we mostly just use that word to refer to web and it seems somewhat strange to put the name of a working group there in the first place.

I don't think we currently surface the word whatwg in APIs, it's only used to name files under benchmark and test so it should be fine to simply rename those files maintenance-wise.
