[LayoutNG] Runtime flag for block fragmentation.

Add a LayoutNGBlockFragmentation flag (which implies LayoutNG). Not
enabled by default. When enabled, we will use NG's current block
fragmentation implementation (which is incomplete). When disabled, we'll
fall back to legacy layout for anything that needs block fragmentation.

This flag is deliberately not enabled on the layout_ng trybot, so now a
bunch of multicol / pagination / printing tests will start to pass
there.

In order to retain test coverage for NG's block fragmentation
implementation, the plan is to enable this new flag in some virtual
testsuite for fast/multicol/ & co. Will deal with that in a separate CL.

Keeping this one open for now. Need to add back testing of NG block fragmentation, so it doesn't silently regress.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/70249752e5bb14719ff69ed4619a61bed9336eb2

commit 70249752e5bb14719ff69ed4619a61bed9336eb2
Author: Morten Stenshorne <mstensho@chromium.org>
Date: Wed Apr 04 19:38:41 2018

Add virtual/layout_ng_experimental/ test suite.

The idea with virtual/layout_ng_experimental/ is for it to
test LayoutNG features that aren't enabled by "default". The
existing virtual/layout_ng/ testsuite, on the other hand, should
only enable the NG feature set that we intend to ship next.

This CL includes some directories relevant to block
fragmentation testing, and enables the runtime feature
LayoutNGBlockFragmentation on those. In the future we may want
to do the same for e.g. flexbox or tables.

The expected results and expectation files here are based on the
LayoutNG expectations prior to CL:976223 (which disabled NG block
fragmentation in the "default" NG feature set), plus some
additional rebaselining, because running a virtual test requires
render tree dumps in more cases, for some reason.
