Bug fix for FreeRTOS#967

The configMINIMAL_STACK_SIZE was defined to PTHREAD_STACK_MIN with cast
to unsigned short. This cast cab be too restrictive and result in
truncation on some platforms. This commit removes this unnecessary cast.

Ensure that the handler2_address_const location will be correctly
aligned when compiled to a separate section.

Add the 'used' attribute to isr_vector to ensure it will not be elided
from the output.

…ections

For these options to be of any use, they must be passed to the
compiler when building object files and then the --gc-sections flag
must be passed to the linker.

Add -ffunction-sections -fdata-sections to CFLAGS and then add
-Wl,--gc-sections to LDFLAGS.

Instead of a set of POSIX-compatible APIs as needed by newlib,
picolibc needs a FILE struct allocated that references a function to
output a single character. Picolibc also doesn't need sbrk as it has
its own version

Picolibc has an internal version of sbrk that uses slightly different
symbol names than the demo provides. Add these in the linker script.

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.
