lib: cpp: Rename CONFIG_CPLUSPLUS to CONFIG_CPP There is no reason for the top-level C++ Kconfig symbol to be called `CPLUSPLUS` when the convention used throughout the Zephyr codebase is to use "cpp" to refer to C++ and the rest of the C++-related Kconfig symbols are prefixed with `CPP_`.

libc/picolibc: Clean up Picolibc Kconfig for C++ libstdc++ is supported with Picolibc only when the toolchain version of Picolibc is use -- libstdc++ must be built using a specific Picolibc build and libstdc++ is included with the toolchain. Ideally, we'd allow the use of the Picolibc module whenever we weren't using the GNU libstdc++, including when using the minimal libc++. However, the obvious dependency settings create a loop: config PICOLIBC depends on PICOLIBC_SUPPORTED config PICOLIBC_SUPPORTED depends on !(GLIBCXX_LIBCPP && "$(ZEPHYR_TOOCHAIN_VARIANT" = "zephyr") config GLIBCXX_LIBCPP depends on NEWLIB_LIBC || PICOLIBC To break this loop, we replace GLIBCXX_LIBCPP in the second block with CPP: config PICOLIBC_SUPPORTED depends on !(CPP && "$(ZEPHYR_TOOCHAIN_VARIANT" = "zephyr") This means that picolibc cannot be used with any C++ apps when using the Zephyr SDK, even when not using the GNU libstdc++. However, Zephyr SDK 0.16 will come with an additional Kconfig file that includes: config PICOLIBC_SUPPORTED def_bool y depends on "$(ZEPHYR_TOOLCHAIN_VARIANT)" = "zephyr" This will override the Kconfig bits included in Zephyr and allow use of the Picolibc module with C++ code, including using the minimal libc++ bits.

CPP: fix static objects init for MWDT toolchain The constructors of static objects are stored in ".ctors" section. In case of MWDT toolchain we have incompatible ".ctors" section format with GNU toolchain. So let's use initialization code provided by MWDT instead of Zephyr one in case of MWDT toolchain usage. As it is done for GNU toolchain We call constructors of static objects but we don't call destructors for them.

GNU-compatible initialization of CPP static objects
lib: cpp: Rename CONFIG_CPLUSPLUS to CONFIG_CPP There is no reason for the top-level C++ Kconfig symbol to be called `CPLUSPLUS` when the convention used throughout the Zephyr codebase is to use "cpp" to refer to C++ and the rest of the C++-related Kconfig symbols are prefixed with `CPP_`. This commit renames the Kconfig `CPLUSPLUS` symbol to `CPP` in order to better align with the de-facto standard naming convention used throughout the Zephyr codebase, and deprecates the old `CPLUSPLUS` symbol.
