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.

Improve the quality of absl::Hash<std::vector<bool>>.
This previously dispatched to std::hash<vector<bool>>, which suffers from trivial collisions on many platforms. (They often hash the internal words but no size info, so that, e.g., {1, 1} and {1, 1, 0} collide.)
Also extended the unit test to exercise this.

Improve flag_benchmark reproducibility, test multiple threads
This adds multiple threads to the flags benchmark, and also uses some
linker magic to ensure that the defined flags are mapped to a consistent
alignment regardless of other code changes in the benchmark binary.
The benchmark performance in multiple threads is somewhat sensitive to
the alignment of the FlagImpl class, depending on whether the flag value
and the absl::Mutex are on the same cacheline or different ones. Making
all flags be cacheline-aligned would probably waste too much memory,
so this CL instead just makes the memory alignment consistent within the
tests.

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.
