kernel: Support platforms with runtime timer freq for thread init_delay

Browse source 
Platforms that determine their basic timer frequency at runtime instead of
build time cannot compute thread initialization timeouts during
compilation.

Switch back to storing the init_delay value in milliseconds and perform the
conversion to a k_timeout_t at runtime.
