migration: Remove block migration

Browse source 
The block migration has been considered obsolete since QEMU 8.2 in
favor of the more flexible storage migration provided by the
blockdev-mirror driver. Two releases have passed so now it's time to
remove it.

Deprecation commit 66db46ca83 ("migration: Deprecate block
migration").
