[gn] Remove custom GN rules for abseil-cpp

Previously due to how Skia used Dawn, we had to maintain a separate
custom set of build rules for abseil-cpp. Since Skia has moved to
using the CMake build for Dawn, we can now remove these rules.

When moving to use the true abseil-cpp GN rules, I have migrated our
targets to depend on the top-level target, instead of manually
converting all of the targets we directly use, since at this point due
to transitive dependencies we are including most of abseil-cpp anyway.

I retained the custom config to suppress some warnings coming from
abseil-cpp, since otherwise I was getting build failures due to
'-Werror' and the abseil-cpp headers being included. This could be
worked around in other ways like suppressing these warnings at the
inclusion site, turning off the related warnings for the entire build
or if GN supported system libraries/headers, but I decided to just
retain our existing fix.

This requires rolling abseil-cpp and adding //tools/win in DEPS.
I have also adjusted various DEPS hashes related to the toolchain to
match those used by ANGLE. Since Windows was producing missing symbol
errors, so they likely had gotten out of sync, and ANGLE's builds are
working with abseil-cpp.
