Brandon Jones 020d69905e Added Abseil as a third-party dependency 
Using the version in the Chromium repo in order to make use of the .gn
files it contains.

Doing so also appears to require us to switch where we pull googletest
from so that the directory structure matches what the Abseil build
config expects. Fortunately this doesn't seem to cause issues in our
tests.

# When upgrading to CMake 3.11 we can remove DAWN_DUMMY_FILE because source-less add_library
# becomes available.
# When upgrading to CMake 3.12 we should add CONFIGURE_DEPENDS to DawnGenerator to rerun CMake in
# case any of the generator files changes. We should also remove the CACHE "" FORCE stuff to
# override options in third_party dependencies. We can also add the HOMEPAGE_URL
# entry to the project `HOMEPAGE_URL "https://dawn.googlesource.com/dawn"`
