Roll Abseil and QUICHE

QUICHE needs to be rolled to Open Screen in order to permit removing the
obsolete QuicSession::CreateIncomingStream() method.

The new version of QUICHE requires absl::down_cast, so Abseil needs to
be rolled to permit QUICHE to be rolled.

The new version of Abseil no longer includes a definition of memcpy()
in string_view.h, which makes compilation fail on GCC with older
versions of QUICHE. For this reason, QUICHE and Abseil need to be
updated in the same CL.

Manual changes:
- Update abseil/BUILD.gn. Only add new source files that are actually
  used, for consistency with existing practice.
- Add -Wno-deprecated to the protobuf BUILD.gn, as protobuf uses
  absl::disjunction, which is deprecated in the newer versions of
  Abseil.
