Avoid using value move/swap and delete those functions from slot_policy types. There was only one use of params_type::move in `erase`.

We were using `init_type`s for temp values that we would move into slots, but in this case, we need to have actual slots. We use node handles for managing slots outside of nodes.
Also, in btree::copy_or_move_values_in_order, pass the slots from the iterators rather than references to values. This allows for moving from map keys instead of copying for standard layout types.
In the test, fix a couple of ClangTidy warnings from missing includes and calling `new` instead of `make_unique`.

Small refactoring to work towards allowing for node_btree_* containers.
- Change common_params::transfer to rely on slot_policy transfer instead of manually doing construct/destruct. Transfer is not construct/destruct for node containers.
- Move maps' value_compare into btree.h from btree_map.h so it can be reused for node_btree_map.h.
- Also add a test for maps' value_compare protected members.

Add a parameter pack to absl profile to allow profiles to separate
dynamic data from static data that is available at constructor-time.
Background: `inline_element_size` is effectively constant, but there
is a data race between its initialization and its access. We had fixed that race by making
inline_element_size atomic. This CL changes `inline_element_size`
back to a non-atomic integer, and provides a way for all profiles to
provide Register()-time values.

We note that the most important API differences are mentioned in the next paragraph and that other API differences are minor. An example of another minor API difference is the note about std::launder in the comment for `extract`.
Motivation: readers shouldn't feel like they need to read the entire header file to understand why b-tree containers are not "drop-in replacements" for STL containers.

Change many distribution tests to use pcg_engine as a deterministic source of entropy.
It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests.
Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values.
This changelist does the latter.
