[M96-LTS] Use IsErrorDocument() to prevent BFCacheing of interstitials and errors.

M96 merge issues:
Tests not present on M96:

• back_forward_cache_basics_browsertest.cc
• back_forward_cache_browsertest.h
• back_forward_cache_internal_browsertest.cc
  chrome_track_event.proto:
• changed code (tracing) doesn't exist on M96, discarded
  all changes
  back_forward_cache_browsertest.cc:
• conflicting includes
• removed NavigateAndBlock, which would be called on
  on back_forward_cache_browsertest.cc (not present in M96)
  page_handler.cc:
• conflicting case statements on NotRestoredReasonToProtocol
  back_forward_cache_can_store_document_result.cc:
• NotRestoredReasonToTraceEnum not present on M96
• conflicting case statements on NotRestoredReasonToString
  back_forward_cache_metrics.h:
• conflicting entries for NotRestoredReason enum

In the bug, a crash occurs because we try to cache an interstitial. We
catch some error documents via status codes etc but interstitials do
not consistently set those. Checking IsErrorDocument() is more reliable.
