This crash was due to the fact that we were passing `nullptr` as a `const
char*` parameter and relying on that implicitly converting into an empty
`absl::string_view`. `absl::string_view` supports that functionality, but
starting with C++17 its behavior changes since it's just a type alias for
`std::string_view`. `std::string_view` does not have any special conversion for
nullptr and so we were just getting crashes.

This also adds tests for C++17 and C++20 to prevent further regressions.

In both cases a `size_t` was being converted to a `uint32_t`. These headers are used from application code, or at least from generated code, and the application may be compiling with more warnings enabled than normal.

This PR replaces the descriptor name validation regex with a validation method. This change allows the `System.Text.RegularExpressions` engine to be trimmed away in published apps that do standard protobuf serialization.

There are some other usages of `Regex` in Google.Protobuf, but they in `JsonParser`. They are only included in a published app if `JsonParser` is used.

Another benefit is a slightly faster app startup time. The removed regex was compiled, which has a high-ish fixed cost.

This turns the constexpr constructors into templates to silence errors when constexpr isn't valid.  We are also switching to 12.2 for GCC/cmake tests to prevent regressions (9.5 and 13.1 are already tested by GCC/bazel tests).
