[text-wrap-pretty] Run `NGScoreLineBreaker` if `text-wrap: pretty`

This patch invokes `NGScoreLineBreaker` if `text-wrap: pretty`,
connecting all pieces landed so far. In other words, this
patch makes `text-wrap: pretty` effective.

There are some failures when `NGScoreLineBreaker` is enabled
by default for all web_tests. They will be investigated more
in following patches.

A test is added to `wpt_internal` because the algorithm is
UA-defined. Two expectations are because the current score
depends on the zoom factor and that it produces different
results depending on the device-scale-factor. This will be
revisited when reviewing penalties.

This patch should have no behavior changes because all changes
are under a runtime flag.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
