Make concept based table IDs 64 bit

While we still have some headroom for the datasets we work with at the
moment, keeping the IDs of concept table based tables (inheritance) at
32 bit would have been a limit at some point. Already we see large
segmentation datasets that make this headroom rather small. Therefore
this migration will rewrite all concept based tables as well as tables
that reference them through foreign keys so that 64 bit IDs are used.

This migration also updates the review table to use 64 bit IDs. It also
fixes the history views of the catmaid_sampler table, which haven't been
kept up to date with column changes.

In addition a lot of missing foreign key constraints have been added.
They shouldn't have a big import on performance and in fact no real
difference could be measured.

The column order of concept changed slightly to improve the column
alignment and reduce padding. So far we wasted 4 Bytes per row, because
project_id occupied 4 Bytes and required 4 Bytes of padding, because it
was followed by a bigint. This is changed now and no more padding is
needed. This also lowers the impact on storage of the change to 64 bit
IDs.

Also, the indices backing the primary keys of many semantic tables
include now additional data like the class_id for class instances and
the relation_id for some relation instance types. This Postgres 11
feature allows to use more index-only scans.

Fixes catmaid/CATMAID#1848
