arm64: factor out current_stack_pointer
We define current_stack_pointer in <asm/thread_info.h>, though other files and header relying upon it do not have this necessary include, and are thus fragile to changes in the header soup. Subsequent patches will affect the header soup such that directly including <asm/thread_info.h> may result in a circular header include in some of these cases, so we can't simply include <asm/thread_info.h>. Instead, factor current_thread_info into its own header, and have all existing users include this explicitly.
