coco/tdx-host: Expose P-SEAMLDR information via sysfs

TDX module updates require userspace to select the appropriate module
to load. Expose necessary information to facilitate this decision. Two
values are needed:

- P-SEAMLDR version: for compatibility checks between TDX module and
		     P-SEAMLDR
- num_remaining_updates: indicates how many updates can be performed

Expose them as tdx-host device attributes visible only when updates
are supported.

Note that the underlying P-SEAMLDR attributes are available regardless
of update support; this only restricts their visibility to userspace.
