[DevTools] Named hooks transient errors

[bvaughn]

Sometimes named hooks inspection will seemingly fail the first time then work the second time. (e.g. using a DEV build of Facebook.com, the <CometTheme> component currently does this).

I think this might indicate a timeout during inspection? (So the retry is fast because everything is cached.)

<CometPressable> is another example that (silently) fails to parse any names.

Edit I believe this is because the selected component type is forwardRef rather than a function component.

I think this was actually because the hooks objects get recreated between inspections. Switch to keying them by stable fileName+lineNumber+columnNumber string instead
