Demo/CORTEX_M3_MPS2_QEMU_GCC: Add option to build with picolibc
When built with PICOLIBC=1, selects picolibc as the C library by
removing the newlib-nano linker flags and adding
--specs=picolibc.specs to the compiler flags. This also selects the
integer-only printf variant provided within picolibc to reduce flash
use by adding -DPICOLIBC_INTEGER_PRINTF_SCANF.
