libc/picolibc: Support picolibc's assert-verbose option

This option in picolibc switches the assert macro between a chatty version
and one which provides no information at all. This latter mode avoids
placing the associated strings in memory.

The Zephyr option is PICOLIBC_ASSERT_VERBOSE and it is disable by default.
