Bump Bazel version to 7.0.0
Also update C++-toolchain to use modern C++ features. This is only
relevant for dependencies, that are built from source, like Protobuf and
other transitive dependencies (e.g. abseil-cpp).
We are doing this to synchronize with the Bazel itself, that bumped C++
toolchain in 7.x release line.
The original commit message in this PR: [1]:
In upcoming changes, we'd like to have the ability to use C++17 features.
This ensures that such code will build successfully on the various CI
platforms, regardless of the C++ standard version the compiler defaults
to.
