[BOOTDATA][IMM32][NTUSER] Set "LoadIMM" to zero

We set "LoadIMM" to zero in order to disable Cicero.
The name of "LoadIMM" is a brain-dead name. This name
means Cicero despite of its name (brain-dead).
They use a human-confusing name intentionally.

JIRA issue: CORE-19320

- Set HKLM\SOFTWARE\Microsoft\Windows NT\
  CurrentVersion\IMM:LoadIMM to 0.
- Add warning comments to the brain-dead name "LoadIMM".
