coco/guest: Move shared guest CC infrastructure to drivers/virt/coco/guest/
In preparation for creating a new drivers/virt/coco/host/ directory to
house shared host driver infrastructure for confidential computing, move
configfs-tsm to a guest/ sub-directory. The tsm.ko module is renamed to
tsm_reports.ko. The old tsm.ko module was only ever demand loaded by
kernel internal dependencies, so it should not affect existing userspace
module install scripts.
The new drivers/virt/coco/guest/ is also a preparatory landing spot for
new / optional TSM Report mechanics like a TCB stability enumeration /
watchdog mechanism. To be added later.
