soc/intel/alderlake: Check MANUF_LOCK when logging manufacturing mode

As per Intel doc #627331 Section 3.6.1 "Intel CSME Production Machine
Determination", from ADL onwards there are three criteria which
determine whether a device is in production mode:
1. Fuses are programmed
2. SPI descriptor is locked
3. Manufacturing variables are locked

When logging whether the device is in manufacturing mode, 1 and 2 are
already checked. Add a check for 3 as well.

Also add logs for each individual criteria so it's easy to tell why the
overall Manufacturing Mode is set or not.
