build/cmake: Add toolchain C++ library linking for all platforms.

Browse Source 
Extend CONFIG_LIBCXXTOOLCHAIN support to all remaining platforms
in CMake builds by explicitly locating and linking libstdc++.a
from the toolchain. This prevents build failures caused by STL
header/library mismatches where toolchain headers are included
without the corresponding library.
* Adds nuttx_find_toolchain_lib() calls for all platforms.
* Aligns CMake behavior with Make build system.
