Update XML output to properly print special characters. Non printable characters are skipped in output. All the "whitespace-like" (including \t, \r, \n) characters printed as plain space ' '.

This is only a workaround, working only with gcc/clang, while waiting
for a better long term fix not using std::aligned_storage, which is
tracked by b/260219225.

Add a unit test that captures the current behavior of formatting of char types and char-backed enum types through StrCat(), StrFormat("%v"), and Substitute().

This test allows us to modify the behavior in this space without introducing undesired changes elsewhere.

Note that RE2 has taken a dependency on Abseil, so the `main` branch
should be used from now on. The `abseil` branch will go away soon...

This avoids the need to use filesystem APIs just to write to stderr, which emscripten implements the same as this under the hood.

The fallback isn't totally portable, even within POSIX, but we can special case any future platforms where it's not just like this change does for Apple.

hash_test.cc leans heavily on INSTANTIATE_TYPED_TEST_SUITE_P, which is
quite memory- and CPU-hungry. Split a few heavyweight tests into a new
hash_instantiated_test.cc, reducing peak RAM consumption (or, on
multicore systems, compilation time).

The non-RAW_ versions provide better output but weren't available when most of these tests were written.

There are just a couple spots where RAW_ is actually needed, e.g. signal handlers and malloc hooks.

Also fix a couple warnings in layout_test.cc newly surfaced because the optimizer understands CHECK_XX differently than INTERNAL_CHECK.

We add this declaration to compensate.

This change includes support for both GCC 12 and 13 since we
were only testing GCC 11 before this change.

This uses the same flags that Clang based builds use for Windows/Linux.

A future change will add floating point related flags and some warning
suppressions.  So, we clone the section rather than just change the check
at line 77.
