Reland of Change base::Value::ListStorage to std::vector<base::Value>

The compilation on ChromeOS failed for the original CL
(http://crrev.com/2811673002), it is likely that a simple rebase fixes the
issue.

This patchset is equivalent to issue 2740143002 at patchset 14, simply another
rebase took place.

Original description follows:

This CL is a first step to inlining base::ListValue. It is proposed to use an
std::vector<base::Value> as the underlying ListStorage. This CL implements the
change and updates the code accordingly.
