Instead of fetching dependencies by default, we will first look for a local installation and only fetch as a fallback. Two new options are added for forcing either of these behaviors. protobuf_FORCE_FETCH_DEPENDENCIES will always fetch dependencies, and protobuf_PREVENT_FETCH_DEPENDENCIES will never do so.

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.

This leaves the decision of which C++ version to use up to our users. We still have a static_assert in port_def.inc that will prevent pre-C++14 usage.

If `-Dprotobuf_USE_EXTERNAL_GTEST=ON` is passed to CMake, it will use an external Google Test copy (i.e. by calling `find_package(GTest REQUIRED)`) rather than the one provided as a submodule.
This makes sense for larger projects that might already include Google Test and want to use a more standard CMake approach.
Also updated build instructions with this information, and more idiomatic usage.

Convenience feature: enable users to test via the familiar `ctest` command rather than making the `check` target.
They would be able to use the familiar CMake pattern:
```
cmake -S source/protobuf -B build/protobuf ...
cmake --build build/protobuf
ctest --test-dir build/protobuf
cmake --install build/protobuf
```
This is a follow-up to 9f447fc9d3da93da29b8301f1a8ca57b1ea812d7
- Improved readmes.
- Fixed incorrect definition of kint32min.
- Fixed absolute output paths on Windows.
- Added info to Java POM that will be required when we upload the
package to a Maven repo.
