migration: Remove non-multifd compression

Browse source 
The 'compress' migration capability enables the old compression code
which has shown issues over the years and is thought to be less stable
and tested than the more recent multifd-based compression. The old
compression code has been deprecated in 8.2 and now is time to remove
it.

Deprecation commit 864128df46 ("migration: Deprecate old compression
method").
