Nadav Har'El 35d95d6887 merge: Add postimage implementation

Merged pull request https://github.com/scylladb/scylla/pull/5996 from
Calle Wilund:

Fixes #4992

Implements post-image support by synthesizing it from
pre-image + delta.

Post-image data differs from the delta data in two ways:

1.) It merges non-atomics into an actual result value
2.) It contains all columns of the row, not just
those affected by the update.

For a non-atomic field, the post-image value of a column
is either the pre-image or the delta (maybe null)

Tested by adding post-image checks to pre-image test
and collection/udt tests
