- Implement `GetFirmwareType` and improve existing API test for it
- Move (Get/Set)FirmwareEnvironmentVariableEx(A/W) to kernel32_vista_static and export them when NT version >= 6.2
Addendum to 4c8a2a8815. CORE-11954
Create kernel32_vista_static library and link both kernel32_vista and kernel32 to it.
Export some vista functions from kernel32.
Export BaseProcessInitPostImport for Vista+, too, because ntdll needs to dynamically link to it.
