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
Add implementations of open(2), mkdir(2), stat(2),
etc. that support long paths under Windows (paths
longer than MAX_PATH in <windows.h>, which is 260
characters).
The implementations are in a separate namespace
(google::protobuf::internal::win32), so they won't
collide with the standard implementations in
<io.h>, but after importing them with `using` they
can be drop-in replacements.

The check target did not depend on the test_plugin binary, so this would
cause "make check" to fail at times because of the absence of
test_plugin. This change adds a dependency on test_plugin so that it
will always get built before the tests are executed.
A series of improvements:
- Improved Protobuf module compatibility (disabled by default);
- Hide advanced settings;
- Added build tree configuration;
- Added build of examples.
