k_uptime_get_32() function

Get system uptime (32-bit version). This routine returns the lower 32-bits of the elapsed time since the system booted, in milliseconds. This routine can be more efficient than k_uptime_get(), as it reduces the need for interrupt locking and 64-bit math. However, the 32-bit result cannot hold a system uptime time larger than approximately 50 days, so the caller must handle possible rollovers.
