Hermès Bélusca-Maïto 005f75bd61 [RTL] x64/ARM: Alias RtlpBreakWithStatusInstruction to DbgBreakPointWithStatus; x64: fix a bug.

RtlpBreakWithStatusInstruction is just a label for KD.

On machines that have register calling conventions (basically all except
x86), the `Status` parameter for `DbgBreakPointWithStatus` is stored in
the first argument register.

https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/wdm/nf-wdm-dbgbreakpointwithstatus

On the x64 platform, `DbgBreakPointWithStatus` only uses the ECX register
and leaves EAX untouched. Verified on Windows.

RTL restrictions:

ExAllocatePool (and friends) must be used exclusively. RtlAllocateHeap (and friends) must NOT be used! ExAllocatePool (and friends) translate to RtlAllocateHeap (and friends) in ntdll\rtl\libsupp.c.

RtlEnterCriticalSection (and friends) must be used exclusively. ExAcquireFastMutex (and friends) must NOT be used! RtlEnterCriticalSection (and friends) translate to ExAcquireFastMutex (and friends) in ntoskrnl\rtl\libsupp.c. This means that RtlEnterCriticalSection (and friends) can NOT be used recursively in RTL. The reason for choosing RtlEnterCriticalSection (and friends) over ExAcquireFastMutex (and friends) is that the FAST_MUTEX struct is smaller than the RTL_CRITICAL_SECTION struct.
