lib/libc: Mark picolibc as providing full C library support

Select FULL_LIBC_SUPPORTED when picolibc is available. Add picolibc as a secondary default C library when REQUIRES_FULL_LIBC is selected. This is necessary as tests gated on FULL_LIBC_SUPPORTED need to be sure that a full C library will be selected -- if only picolibc is available, those tests will need to select that. This should permit use of a picolibc-only crosstool-ng toolchain in testing. Signed-off-by: Keith Packard <[email protected]>
