[REACTOS] Use the RT_* resource type defines where possible (#6023) 
And use the self-documenting `MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL)`
instead of `0` for the `LDR_RESOURCE_INFO::Language` structure member.

[REACTOS] Usage improvements for some RtlFindMessage invocations (#6023) 
Use `RT_MESSAGETABLE` and `MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL)`
instead of hardcoding their values.

[NTOS:EX] Check whether the boot-time drivers are safe to use on MP systems (#7744) 
Invoke the MmVerifyImageIsOkForMpUse() helper. If the boot-time driver
only supports a uniprocessor system, bugcheck with UP_DRIVER_ON_MP_SYSTEM.

https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x92--up-driver-on-mp-system

Note that we don't do this check very soon at boot time (e.g. in
MiReloadBootLoadedDrivers or MiInitializeLoadedModuleList), but only
after loading the drivers' debug symbols (if any).
The reason is simply to ease debugging in case we bugcheck: this allows
having the debugger set up with the symbols for this driver.

For automatic and manual driver loading, MmVerifyImageIsOkForMpUse()
is invoked by MmCheckSystemImage() but in this case, there is graceful
failure and no bugcheck.

[NTOS:EX/KE][HALX86] Add support for NUMPROC, BOOTPROC, MAXPROC, ONECPU boot switches (#6024) 
These SMP-specific switches allow to test and control configurations
with various number of CPUs on multiprocessor systems.

- NUMPROC: maximum number of logical processors that can be started
  (including dynamically, not currently supported by ReactOS) at run-time.

- BOOTPROC: maximum number of logical processors that can be started at
  boot-time.

- MAXPROC: forces the OS to report the maximum possible number of CPUs
  as existing on the system.

- ONECPU (MP HAL-only boot switch): causes the HAL to only use one
  (the boot) CPU on a multiprocessor system. Attempting to start other
  processors will fail.

For more information, see:

[NTOS:OB] Allow ObpCaseInsensitive to be configured via registry (#7751) 
This feature can be controlled by the system policy:
"System objects: Require case insensitivity for non-Windows subsystems"
https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-r2-and-2012/jj852277(v=ws.11)

It is also used in conjunction with NTFS to get system-wide filesystem case-sensitivity:
https://www.betaarchive.com/wiki/index.php/Microsoft_KB_Archive/929110

This is controlled with a REG_DWORD value named `ObCaseInsensitive`
inside the registry key
`HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Kernel` .

Object case (in)sensitivity check is done in the ObpLookupObjectName() helper.
The `ObpCaseInsensitive` variable is used to retrieve the data,
hence it needs to be a ULONG.

70bf3bb8fa [NTOS:KDBG] Add back 'cregs' command 
This command was removed in commit baa47fa5e0
because there was no way to get the CRx registers from a CONTEXT structure.
Previous code was also displaying current GDTR/LDTR and IDT.

Rewrite the code to use KdSystemDebugControl(SysDbgReadControlSpace, ...)
to get CRx, GDTR/LDTR and IDT values just before entering debugger.

[NTOS:EX] HACK: on livecd, disable security features in NtSystemDebugControl 
WinDBG can do some local debugging using 'windbg -kl'. In that case,
WinDBG tries to directly use NtSystemDebugControl. If this function
returns an error, WinDBG extracts a driver from its resources.
WinDBG will send IOCTLs to this driver, and this driver will call
KdSystemDebugControl.

However, on livecd (where %SYSTEMROOT% is read-only), WinDBG is unable
to extract the driver from its resources, and can't use the driver to
call KdSystemDebugControl.

As a work-around, allow all control classes in NtSystemDebugControl
in case of livecd.
WinDBG local debugging now also works on livecd (windbg -kl).
