When building protobuf with BUILD_SHARED_LIBS disabled, conformance_test_runner should link jsoncpp_static but not jsoncpp_lib.

- Make sure the hash flooding test actually does hash flooding. The technique used to choose the inputs stopped working when random seeding was added. Now we assert trees are used in the test so it won't silently break again.
- Improve test coverage for tree buckets.
- Update the hash flood test to use absl::Time/Duration.
- Improve the map tests to use long strings. This way we can test that the values are being properly destroyed. Small strings could be leaked without side effects because of SSO.

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.

CMake has fairly strict backwards compatibility behavior. Saying `cmake_minimum_required(VERSION 3.10)` has two effects:
- It requires CMake to be version 3.10 or higher
- It configures CMake to behave exactly as it did in version 3.10
The code used to override some policies to get newer behavior if it was available. The alternative syntax in this PR says "require at least 3.10, and use the behavior (when available) up to 3.26". We can omit policy overrides by doing so. It does not seem like any other policies are important, so we can use the simpler syntax.

- Move several operations from MapField/DynamicMapField into TypeDefinedMapFieldBase.
- Change MapIterator to keep an iterator inline instead of new/delete.
- Change RepeatedPtrField usage to always be RepeatedPtrField<Message>.

Warnings in header files can be a problem for consumers that enable `/WX` (or `-Werror`). In this case, using `... & -align` produces a warning (C4146) with MSVC. The fix is to use equivalent expression `... & ~(align - 1)`, which was already used in the same file.

On Wndows, `size_t` is 64-bits, and `int` is 32-bits. That makes conversions from `size_t` to `int` potentially lossy, and they generate warnings. In this case an `int` variable was assigned to `size_t` and then passed to functions consuming `int`. Seems simpler to use `auto` and avoid these problems altogether.

When the protobuf libraries have been compiled as shared libraries the users of the library need to add `-DPROTOBUF_USE_DLLS` to their build line. Otherwise some symbols are missing.
Fixes#12699
FWIW, I am not sure this is an ideal fix. It may be better to fix the headers such that no macros change the ABI.
