Reland "[lldb] Reland 2402b32 with /H to debug the windows build issue (llvm#101672)

This reverts commit 9effefb.

With the include order in ScriptedProcessPythonInterface.cpp fixed
(though I cannot explain exactly why it works) and removes the /H flag
intended for debugging this issue.

I think it is something to do with Process.h pulling in PosixApi.h
somewhere along the line, and including Process.h after lldb-python.h
means that NO_PID_T is defined to prevent a redefinition of pid_t.

(cherry picked from commit 9d07f43)
