[massive store] Reintroduce methods that are necessary to properly handle master/slave configuration

[massive store] Follow configuration of the metadata generator
Don't drop constraints and indexes for tables that are ignored by the metadata
generator given to the store. One may now easily disable insertion of e.g.
created_by / owned_by by removing them from the MetadataGenerator.META_RELATIONS
set, in which case indexes for associated table won't be removed by the massive
store.

[dataimport] make MetadataGenerator.META_RELATIONS customizable
This should be done on the instance rather than on the class

[massive store] Rework constraint/index handling
The basic idea is to keep the primary constraint on entities.eid since it's
heavily used in metadata insertions. Other option would have been to drop /
recreate but its very costly on big database, and the index is used for
insertion into the entities table itself, so it's not worth droping it at a
first glance.
Also, keeping it avoids to systematically drop all constraints which depends on
it. We may thus now lazily drop constraints, only on insertion of some
etype/rtype for the related table.

[massive store] Lazy removal of constraints and metadata indexes
They should not be removed during store's init, because we may want to query the
database with its index between store creation and call to prepare_insert* (e.g.
to build the extid2eid map).
Along the way:
* rename drop_metadata_constraints into drop_metadata_indexes, because that's
what it does
* rework a bit impacted tests

[repository] Drop the index on entities.type
It should be now only used in maintenance queries in checkintegrity. Those are
not worth maintaining it.
Closes #15538317

[source] Drop source mapping handling
It was only used by the cwxmlparser which has been deleted. This is too complex
for litle benefit, we don't want to maintain that in cubicweb.

[repository] Drop the entities.extid column and associated cache
This was not necessary anymore with promoted usage of the new data import API.
Turn repository's _type_extid_cache to _type_cache with only the entity's type
as key.
This introduces an backward incompatible change: entity_metas dict doesn't
contains anymore the extid key, but it doesn't seem used at all anywhere, so
this sounds acceptable.
Closes #15538317
