[IMM32] Use Imm32IsImmMode and Imm32IsCiceroMode macros (#3971)

- Define Imm32IsImmMode, Imm32IsCiceroMode and Imm32Is16BitMode macros in "precomp.h".
- Improve Imm32InquireIme and Imm32CleanupContext functions.
- Add IME_SYSINFO_WINLOGON and IME_SYSINFO_WOW16 macros (from DDK) in psdk/imm.h.
- Modify CtfImeInquireExW and CtfImeSelectEx prototype.
