Buildings from ways and multipolygons are loaded in table `osm_building_polygon`. But a table for `osm_building_multipolygon` is also loaded, the content is not used except to ensure an `osm_id` is from a multipolygon. To check if the object is from a multipolygon we have only to check if `osm_id` is negative. It is the counter part of e0c8ece375/layers/building/building.sql (L89)
I checked the objects are the same after this change.
Make a few more mappings declarative, and removes values declared in both SQL and the yaml file.
Here's the diff comparing `build/tileset.sql` in master vs the new PR. The changes are mostly stylistic, except when a nested `if` statement is expanded into individual `if ... and ...` conditions (logically identical)

quicker and cleaner diagram image generation.
Remove etl-graph and mapping-graph targets - redundant
Also, the obsolete "fields" is still in Imposm's code and both names are accepted,
but "fields" is not documented anywhere (PR submitted), and could be removed at any moment.
Our docs were not supporting it until this PR, so renaming it at the same time.
Several images have been updated due to a more inclusive mapping scan
Requires https://github.com/openmaptiles/openmaptiles-tools/pull/147 (merged)
Minor code cleanup:
SQL already returns NULL in the "WHEN" condition
if it is not matched by any of the cases.

* Use _resolve_wikidata in layer mapping.yaml
Mark all tables that should not be populated with the Wikidata
international labels with a special OMT-specific flag.
This should be ok to merge even before the new tools version
is used because imposm seems to ignore anything it doesn't understand.
The next tools version will remove it when generating imposm mapping file.
* Migrate to new Wikidata importer
Uses latest tools to populate the wd_names table
during the quickstart. This can be merged already,
or we can wait for the next tools version.
* Move simplified border tables to OMT as MAT VIEWs
Consolidate derived table creation in OMT repository.
Move all non-original simplified geometry tables from import-osmborder
image to this repo, allowing further optimization.
Later we can remove derived table creation fro mthe import-osmborder image.

Move materialized view creation from the tools repo.
This PR should be merged before the https://github.com/openmaptiles/openmaptiles-tools/pull/115
Merge the other PR shortly after this one to avoid doing the same work twice - first creating simplified table, then dropping it and recreating them as materialized views.
Tag all SQL materialized views with a machine-readable comment
to indicate that this materialized view can be created without
data:
/* DELAY_MATERIALIZED_VIEW_CREATION */
In the next version of tools this comment can be optionally
replaced with the "WITH NO DATA" parameter, thus allowing
a much faster execution of the SQL script. All materialized
viewes will be populated with data in parallel afterwards
using the `refresh-views` tools script.
Simplify some of the OSM->OMT field value mappings using declarative syntax.
This approach is not for all cases, but in many it removes
the need of storing the same field in both the .yaml and .sql files.
TODO: support more complex AND/OR cases
* Use unified tools version for all images
* do not start postserve as part of quickstart, but added a help message how to start it
* wait for SQL start with pgwait
