Clarify comments about API differences from std::{set,map} in btree headers.
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.

Remove the test for absl::base_internal::NominalCPUFrequency() from OSS code
This is an internal-only function that should never by called by OSS code.
By its nature fails on unsupported platforms.
Google code has tests for this function on supported internal platforms.
Fixes#1053

Silence -Wunused-value warning newly emitted by ToT Clang.
The value is being intentionally ignored, as the purpose of the call is only to eliminate this overload via SFINAE when `GenT{}` is not constant evaluable.

Provide mutable access to the key in node handles using std::launder when compiled with C++17 or later.
Also, document why we can't provide mutable access to the key without C++17.
Note: we use Policy::mutable_key() because btree already uses Policy::key() internally to get const key access, and we want to avoid calling std::launder unless we need mutable access to the key.

Avoid a costly divide (the division accounts for 10% of the time spent in the function).
When the division is signed, the compiler has to generate a div. When it is unsigned, it can generate a shift: https://godbolt.org/z/vGfTv4. As per the test above the div, we know that the value is unsigned.

Slight restructuring of absl/random/internal randen implementation.
Convert round-keys.inc into randen_round_keys.cc file.
Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts.
Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

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.
