Deflaking MockingBitGen test. Because MockingBitGen can return random values,
it is inherently flaky. For log-unifrom, 2040 is a common enough value that
tests failed unreasonably frequently. Replacing it with a significantly larger
value so as to be much less common. 50000 is a good choice because it is (tied for) the least likely to occur randomly from this distribution, but is still in the distribution.

Remove construction tests for the internal `CompressedTuple<std::any>` instantiation. This was not guaranteed to work for the reasons that `std::tuple<std::any>` copy construction does not actually work by standard specification (some implementations introduce workarounds for this). In GCC9, `CompressedTuple<std::any>` and `std::tuple<std::any>` both fail for the same reasons, and a proper "fix" requires updating `std::any`, which is out of our control.

Enable compile-time enforcement that absl::Substitute patterns to not contain unescaped $ symbols.
absl::Substitute already considers unescaped $ symbols undefined behavior and crashes when it's passed them in debug builds. Some code isn't ever built in debug mode, though, and inadvertently used some unescaped $ symbols, which led to surprising results. This change will prevent that problem from happening in the future.

Add install rules for Abseil CMake.
These are attempted to be limited to in-project installation. This serves two purposes -- first it's morally the same as using Abseil in-source, except you don't have to rebuild us every time. Second, the presence of an install rule makes life massively simpler for package manager maintainers.
Currently this doesn't install absl tests or testonly libraries. This can be added in a follow-up patch.
Fixes#38, Fixes#80, Closes#182
