[PATCH 05/11] ntdll: arm64: Store the real stack pointer in RtlCaptureContext

[Martin Storsjo]

In most cases, unwinding will use the frame pointer anyway, so it
doesn't make much of a difference, but for cases where it won't,
capture the actual stack pointer.

(In most cases on arm64, calling the RtlCaptureContext won't cause
anything extra to be pushed on the stack at that point anyway).

Also fix the vertical alignment for the row above.
