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.

Use getentropy() to get seed material when using glibc >= 2.25
getentropy() uses the getrandom syscall on Linux to avoid file descriptors.
It is never interputed (EINTR) and uses the same source as /dev/urandom.
https://man7.org/linux/man-pages/man3/getentropy.3.html
getrandom has been in the Linux since kernel 3.17
When unavailable (ENOSYS), fallback to /dev/urandom.

fix: work around gcc-4.8 bug in disjunction
See https://godbolt.org/z/i7-AmM for a repro of the bug.
I realize that Abseil no longer supports gcc 4.8 officially
(https://abseil.io/docs/cpp/platforms/platforms), but Cloud C++ still supports
gcc 4.8 officially, and so it would be nice to get this simple fix in.

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.
