Replace the per-family stm32_get_uniqueid() implementations and the two
IP-versioned common variants with a single generic byte-array reader,
arch/arm/src/common/stm32/stm32_uid.c.
BREAKING CHANGE for STM32 M0 families: stm32_get_uniqueid() now always
takes a uint8_t[12] buffer.
Out-of-tree Cortex-M0 code that used the previous prototype
"void stm32_get_uniqueid(uint32_t *uid)" must change its buffer to
"uint8_t uniqueid[12]".
