    Enable Scroll To Text by default

    Enables scroll to text by default for M81. Note we plan to launch via
    Finch for M80.

    Intent to ship with LGTMs:

    This patch also updates web platform test expectations:
    - scroll-to-text-fragment.html now passes; it just needed an extra rAF
      for the fallback to element anchor behavior.
    - scroll-to-text-fragment-security.html has two expected failures, as
      they need to be updated to test cross-origin navigations. I'll make
      this change in a follow-up patch to close bug 1042311.
