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

- 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
here is the reason:
1.clock_systime_timespec(core function) always exist regardless the setting
2.CLOCK_MONOTONIC is a foundamental clock type required by many places

NUTTX_LIBCXX is only basic C++ support, do not support many c++
library function, NUTTX_NOCXXLIB is more suitable.
When NUTTX_NOCXXLIB is select, do not select lower level support.

To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.

Remove TIME_EXTENDED option to more conform C standard
Note: the code/data size increment is small
math library is also needed, however, here are various ways to provide a
math library so CONFIG_LIBM is not now set.
boards/arm/stm32l4/nucleo-l476rg/scripts/Make.defs: Add required
definitiions if libcxx is enabled.
Remove hardcoded -DCLOCK_MONOTONIC from CFLAGS in Make.defs of several configurations. That defintiion is now automatically adding this define when CONFIG_LIBCXX=y.
Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.
