Introduce CordRepBtreeReader
CordRepBtreeReader provides forward navigation on cord btrees with absolute positional (offset) context, iterating over btree data in absl::string_view chunks.

This change adds debug-build enforcement that the inputs to
absl::c_set_intersection are sorted, which is a prerequisite of
std::set_intersection and required for correct operation of the
algorithm.

Change BadStatusOrAccess::what() to contain status_.ToString()
This ensures that on uncaught exception propagation that would cause program termination, the message contains information on the error which caused the failure.
Lazy initialization of what_ is a value judgement: if most callers are expected to call status() not what(), lazy initialization is correct. If most callers are expected to call what(), it should be initialized on construction to avoid atomic operation overhead.

LSC: Standardize access to GoogleTest flags on GTEST_FLAG_GET/GTEST_FLAG_SET
This change is necessary to move Googletest flags out of the testing:: namespace without breaking code. These new macros will continue to be required for code that needs to work both inside Google's monorepo and outside in OSS, but can be used anywhere inside the monorepo.

Place STL exception functions underneath the ABSL_HAVE_EXCEPTIONS #ifdef.
The STL exception functions are not present in the Android NDK, so Abseil fails to build as part of ANGLE in AOSP. This CL places the various STL exception throwing functions inside #ifdef ABSL_HAVE_EXCEPTIONS blocks so they are removed during Android builds since neither ANGLE nor the NDK support exceptions by default.

Fix -Wsign-compare issues.
These lines could theoretically have overflowed in cases of very large stack
traces etc. Very unlikely, but this was causing warnings when built with
-Wsign-compare, which we intend to enable with Chromium.
In none of these three cases is it trivial to switch to a range-based for loop.

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.
