Enabling small C library option and deprecating uARM toolchain
 - By default, Mbed OS build tools use standard C library for all supported toolchains. It is possible to use smaller C libraries by overriding the "target.default_lib" option with "small". This option is only currently supported for the GCC_ARM toolchain. This override config option is now extended in the build tool for ARM toolchain. - Add configuration option to specify libraries supported for each toolchain per targets. - Move __aeabi_assert function from rtos to retarget code so it’s available for bare metal. - Use 2 memory region model for ARM toolchain scatter file for the following targets: NUCLEO_F207ZG, STM32F411xE, STM32F429xI, NUCLEO_L073RZ, STM32F303xE - Add a warning message in the build tools to deprecate uARM toolchain. - NewLib-Nano C library is not supporting floating-point and printf with %hhd,%hhu,%hhX,%lld,%llu,%llX format specifier so skipping those green tea test cases.
