upb headers are not in `${protobuf_SOURCE_DIR}/src`, so the `string(REPLACE ...)` command fails and the `save-installed-headers.vcxproj` contains an invalid path regarding upb headers, causing a failure in compilation.
Closes#18135

See abseil release notes:
https://github.com/abseil/abseil-cpp/releases/tag/20240722.0
This is necesary pre-work to enable C++17 builds in preparation of baseline C++
upgrade from C++14 to C++17. C++14 support is scheduled to reach EOL on
2024-12-15:
https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md
Interestingly enough, the older Abseil version 20230802.1 is actually OK for
building on macOS with C++17. However, we depend on GoogleTest, and they
transitively depend on Abseil version 20240116.2, which caused Bazel to
implicitly change the Abseil dependency to most recent specified version of
20240116.2:
https://github.com/google/googletest/blob/main/MODULE.bazel
Current builds with C++17 and Abseil version 20240116.2 on older macos versions
that didn't support `std::filesystem::path` would give the following error:
> error: 'path' is unavailable: introduced in macOS 10.15.
With this version upgrade, we pull in an Abseil patch that fixes this issue on
macOS:

This flips the default behavior to "fetch", downloading local copies of required dependencies. This can be disabled by setting `-Dprotobuf_FETCH_DEPENDENCIES=OFF`, in which case we will look for a local installation using find_package. Setting `-Dprotobuf_ABSL_PROVIDER=package` will continue to have the same behavior as before.
See https://protobuf.dev/news/2024-10-02/#replace-cmake-submods for more details.

Before this CL, it was only possible to get CHandles when fetching messages from a map. proto2::cpp does not have this restriction, so we patch this gap in here.
+utilize the new Emit :)
