build: bump abseil-cpp to 20230802.0

[ncaq]

refer bazel-6.2.1 fails to build with gcc-13 · Issue #18642 · bazelbuild/bazel

I use only GitHub because 20230802.0.tar.gz not found in the mirror. Should be test on abseil-cpp by latest.
Because this version is LTS.

This version build on bazel v6, use BAZEL_CXXOPTS='-std=c++14' bazel build //src:bazel-dev. Because bazel v6 use -std=c++0x by default.

It seems that if the version of Bazel used for CI is v6, then of course CI will fail.
Is it really necessary to change -std=c++14 to make it succeed with v6?

[ncaq]

If the Bazel v6 series is the stable version and it is a requirement to be able to build with it, this can be incorporated after Bazel v7 is stable and it is reflected in CI.
Or change -std=c++14.

@sgowroji
As I already commented, it succeeds with Bazel v7, but fails with Bazel v6.

We are in the process of migrating to Bzlmod, can you submit the new version to the BCR?
