KVM: x86: move SMM exit to a new file
Some users of KVM implement the UEFI variable store through a paravirtual
device that does not require the "SMM lockbox" component of edk2, and
would like to compile out system management mode. In preparation for
that, move the SMM exit code out of emulate.c and into a new file.
The code is still written as a series of invocations of the emulator
callbacks, but the two exiting_smm and leave_smm callbacks are merged
into one, and all the code from em_rsm is now part of the callback.
This removes all knowledge of the format of the SMM save state area
from the emulator. Further patches will clean up the code and
invoke KVM's own functions to access control registers, descriptor
caches, etc.
