[PATCH 0/1] MR8317: ntdll,server: Treat Rbp as CONTEXT_INTEGER register.

[Charlotte Pabst (＠CharlottePabst)]

Before this change we've treated Rbp as a CONTEXT_CONTROL register, but it is a CONTEXT_INTEGER register on windows (unlike ebp on i386, which is indeed a CONTEXT_CONTROL register on windows).

This caused issues with debuggers, specifically the Visual Studio 2022 Remote Debugging Server issues a SetThreadContext call with ContextFlags=CONTEXT_CONTROL, without Rbp set, which leads to Rbp getting erroneously zero'd.

Attached a simple test program [capture.c](/uploads/74698f4cd99246880250d6a139777603/capture.c), not sure if this should be part of the ntdll tests instead.
