Push preg_parser and registry_dict changes upstream

preg_parser and registry_dict are used in Chromium OS by authpolicy
code to fetch policy from AD servers. Right now, a custom version of
the two files is checked into platform2 in Chromium OS. This CL
pushes changes made to these files upstream to Chromium, in particular
making them compile outside of Windows. The goal is to eventually use
them in libchrome, so that only one version of the code has to be
maintained and unit tests can be reused.

Both files are compiled for Windows and Chrome OS, even though only
the Windows version is used in Chromium. This is done to ensure the
file compiles OK and won't cause an issue downstream when used in
Chrome OS.

The i18n UTF16 ToLower method has been replaced by an ASCII method for two reasons:
- We don't need it, we always check for ASCII keys. Keys and values are actually converted to UTF8 later and compared using case-insensitive ASCII checks, so if it was a problem, it would already surface.
- More importantly, using i18n would introduce a dependency in Chrome OS on the third-party library icu and we don't want to pull this in.

RegistryDict::ConvertToJSON has been #ifdef'ed out in Chrome OS because it would pull in some dependencies and it is not needed right now.

Moving to V1, we should be able to reuse unit tests if this is fixed.

Stretch goal, though. We could also just copy the unit tests over for now.

libchrome: Add preg_parser and registry_dict

preg_parser and registry_dict are used by authpolicy to fetch policy
from AD servers. Right now, a custom version of the two files is
checked into platform2 in Chromium OS. This CL puts the Chromium copy
of these files into libchrome, so that authpolicy can reuse this code.

authpolicy: Use preg_parser and registry_dict from libchrome

Removes the local copy of the two classes and uses the libchrome
version instead. This fixes the double-maintainance problem.

As a nice side-effect, histogram data is recorded if preg_parser fails.
This code was removed from the authpolicy-copy of preg_parser.
