[Sheriff] Revert "Implement appHistory.entries()"

This reverts commit b2189baeaeeb74a2aa5b53c002944d7cf7fa439e.

Reason for revert: This CL is suspicious for causing webkit leak tests to fail. First build: https://ci.chromium.org/ui/p/chromium/builders/ci/WebKit%20Linux%20Leak/25321/overview

Original change's description:
> Implement appHistory.entries()
>
> Proposal: https://github.com/WICG/app-history
>
> This introduces the entries() function to the appHistory API. It
> returns an array of AppHistoryEntries that represent the subset of the
> back/forward list that is same-origin and contiguous to the current
> entry. This is constructed in NaivgationRequest just before a commit
> is sent to the renderer for cross-document commits. For same-document
> commits, the renderer modifies the existing appHistory object's
> entries_ array directly.
