Provide a special kernel read/write mapped page while in EL0 if compiled
with CFG_CORE_UNMAP_CORE_AT_EL0 and CFG_CORE_WORKAROUND_SPECTRE_BP_SEC.
This page will later be used as a temporary replacement of
thread_core_local. thread_core_local is not completely replaced, the new
memory is only used for temporary storage of registers via the stack
pointer.
