Rework absl::MockingBitGen internal mock registry.
Use a virtual base class with template-specialized derived classes to implement match method rather than taking the address of a function specialization and using casts everywhere.
This combines several of the previously type-erased pointers into a single object, eliminates the separate cleanup container previously used, and eliminates some gratuitous static_cast<>s.

Improve cache-locality for ThreadIdentity and PerThreadSynch.
This is a change based on an observation in RPC benchmarks that shows
significant cycles being spent in waking up a thread, 99.8% of which
was on cache misses. Investigating this a bit more, it turns out to
be due to sharing the cache line with the waiter state.
To fix this issue, the following changes are introduced:
- Reorder fields in PerThreadSync so that it fits in a single cache line
The size of this structure was 80 bytes before this change.
Note: Manually inspected all booleans to make sure they are not modified by
multiple threads concurrently.

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.
