proc: Check whether window is enabled or not

Check the option which indicates whether window is enabled or not.
If the corresponding option is turned off, then do not execute
window related code in proc and lowmem modules.

If the option is turned on,
   - Update window stack each time
   - Active 'ForegroundAppList' config
   - Consider window information during LMK
