KVM: x86: start moving SMM-related functions to new files
Create a new header and source with code related to system management
mode emulation. Entry and exit will move there too; for now,
opportunistically rename put_smstate to PUT_SMSTATE while moving
it to smm.h, and adjust the SMM state saving code.
