devel/abseil: update Abseil C++ to LTS version 20250127.0

As of this release, ABSL_PROPAGATE_CXX_STD is enabled by default
so work-arounds like the one in the `devel/libphonenumber' port
are no longer necessary.

This will be the last release to support C++14. Future releases
will require at least C++17. Note that the port already demands
it as of commit 17ed41b53fd38.
