[libc++] Simplify how the global stream tests are written (#66842)
Instead of relying on Bash, use the builtin Lit commands whenever
possible. The motivation is to stop running %t.exe behind Bash, which
breaks on macOS 13.5 with SIP enabled because DYLD_LIBRARY_PATH isn't
forwarded to the underlying process when running through a protected
process.

[libcxx] Fix using std::wcout/wcin on Windows with streams configured in wide mode
On Windows, the underlying file descriptors for stdout/stdin/stderr
can be reconfigured to wide mode. In the default (narrow) mode, the
charset usually isn't utf8 (as libcxx assumes), but normally a locale
specific codepage (where each codepage only can represent a small
subset of unicode characters).
By configuring the stdout file descriptor to wide mode, the user can
output wchar_t based strings without convesion to the narrow charset.
Within libcxx, don't try to use codecvt to convert this to a narrow
character encoding, but output these strings as such with fputwc.
In wide mode, such strings could be output directly with fwrite too,
but if the file descriptor hasn't been configured in wide mode, that
breaks the output (which currently works reasonably). By always
outputting one character at a time with fputwc, it works regardless
of mode of the stdout file descriptor.
For the narrow output stream, std::cout, outputting (via fwrite)
does fail when the file descriptor is set to wide mode. This matches
how it behaves with both MS STL and GNU libstdc++ too, so this is
probably acceptable.
This fixes https://github.com/llvm/llvm-project/issues/46646, and
the downstream bugs https://github.com/mstorsjo/llvm-mingw/issues/145
and https://github.com/mstorsjo/llvm-mingw/issues/222.
