Fix the install test project, which is doing a mixed-mode build.
This manifests in failure with GCC 11, which defaults to C++17

Also explicitly reference python3 in the test script.
python2 is being removed by some Linux distros.

Use `capacity + Group::kWidth` control bytes instead of `capacity + Group::kWidth + 1`.

We don't use the extra byte - we only need the first `capacity` ones that are valid, the one sentinel byte and then `Group::kWidth - 1` cloned control bytes. For example, in `EmptyGroup()`, where capacity is 0, we use `Group::kWidth` control bytes.

We need to update set_ctrl() to only mirror `Group::kWidth - 1` bytes instead of `Group::kWidth` bytes.

Note: this doesn't actually save memory unless `alignof(value_type)` is one.

Also add/update related comments.

Improve b-tree value_comp() support.

- Don't expose internal adapted comparator functionality.
- Support value_comp() for maps using function pointer comparators.
- For maps, make value_compare's constructor and the member comparator be protected - [reference](https://en.cppreference.com/w/cpp/container/map/value_compare).
