Revert "Speculative load measurement API - preload tracking"

This reverts commit cd66861b870367aa6ca969ec4c3e2c34c3b8909f.

Reason for revert: We are taking a different approach to tackle the use case.

Original change's description:
> Speculative load measurement API - preload tracking
>
> This CL implements the preload tracking portion of the Speculative Load
> Measurement API, exposing preload information on the pagehide event.
>
> Introduces PageHideEvent (extending PageTransitionEvent) with a
> SpeculationData attribute containing preload information. ResourceFetcher
> tracks all preloads and their usage state, which is collected at
> pagehide time.
>
> The feature is gated behind the PageHideSpeculations runtime flag.
>
