Inclusion of mach/mach_time.h by libcxx/src/chrono.cpp breaks
the build on latest MACOS dues to https://forums.developer.apple.com/forums/thread/746737
The interface from mach/mach_time.h is not referenced in chrono.cpp
so it is safe to remove it

Silence two warnings when building libcxx with GCC 12.2.0 and std=c++2b:
libcxx/src/charconv.cpp_CXXFLAGS += -Wno-attributes
- Results from libcxx fallback to use __always_inline__ when exclude_from_explicit_instantiation isn't available.
libcxx/src/locale.cpp_CXXFLAGS += -Wno-attributes
- Results from the expansion of _LIBCPP_CLASS_TEMPLATE_INSTANTIATION_VIS. Should be fine to ignore.
When we build NuttX on macOS, it shows many `sed` messages (and the build still completes successfully):
```text
$ tools/configure.sh pinephone:nsh
$ make
sed: illegal option -- r
```
This is due to the Makefiles executing `sed -r` which is not a valid option on macOS.
This PR proposes to change `sed -r` to `sed -E` because:
- `sed -E` on macOS is equivalent to `sed -r` on Linux
- `sed -E` and `sed -r` are aliases according to the GNU `sed` Manual
- `sed -E` is already used in nuttx_add_romfs.cmake, nuttx_add_symtab.cmake and process_config.sh
- Add __config_site for NuttX.
In libcxx 12.0.0. CMake concatenated __config_site with _config,
which enabled NuttX to build without its inclusion. In 15.0.7, this
file is configured by CMake and included explicitly in __config.
- Add additional include directories.
- Mute always_inline warning.
- Make the download of libcxx/libcxxabi configurable
In the past, predefined macros were generated by define.sh scripts
Now they are generated by concatenating environment variables
In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile

The libcxx-X.Y.Z.src.tar.xz contains a symbolic link to a directory
that not exist as below.
`libcxx-X.Y.Z.src/test/std/pstl -> ../../../pstl/test/std`
Linux and macOS environment have no problem, but it causes an error
when extracting tarball on Windows platform. This symbolic link is not
actually used, so exclude it from extracting the tarball.
This might be specific to gcc or Linux
as I didn't see it with clang + macOS.

wget is missing from some system (like macOS and Windows native),
it's better to use curl to simplify build environment.
