If libcxxabi is not enabled, the toolchain default implementation will be used. However, arm-gcc does not enable thread
support by default, which will cause errors in a multi-threaded environment.
libcxx depends on pthread_key_create

In the following code, even though the application does not use exceptions, an exception is still thrown in libcxx
If libcxxabi is not enabled, the toolchain default implementation will be used. However, arm-gcc does not enable thread
support by default, which will cause errors in a multi-threaded environment.
Therefore, we need to use libcxxabi to ensure normal functions in a multi-threaded environment.

Because `set_source_files_properties` in cmake will overwrite the properties instead of appending them.
This module implements addition and deletion by
first `getting_source_file_property` and then `set_source_files_properties`

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

It seems libcxx needs C++20 from 12.0.0 to 17.0.6: 3b625060fc

libs/libxx: Enforce RTTI for building libcxxabi
It is okay for the application to be built without RTTI (-fno-rrti), but
libcxxabi requires RTTI at least for the library.

libcxx: Remove exiting patches and update libcxx version to 15.0.7
- 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
```
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
