Details

We have a non-spec version of FirstContentfulPaint behind a pref; if we want to support the PerformancePaintTiming spec (FirstPaint and FirstContentfulPaint), we'll need to add them to the Performance API implementation.

Spec: https://w3c.github.io/paint-timing/

We can leave the non-spec version supported for a release if we want, if anyone is using it.

We'll want to update raptor (or the not-yet-landed raptor patches) for fcp when this changes.

Note that if we do this, we should also expose FirstPaint in that api, not just FCP
