[TASK] Have EM only evaluate current ext_tables.sql on installation

The EM changes due to the new automatic DB fields addition for TCA-based
tables come with a small side-effect, namely that all extensions are
now evaluated when doing the SQL create queries.

The introduced changes now only do execute "safe" DB updates, but not
limited to an extension, but for all installed extensions.
Thus, non-safe DB operations are not taken into account for an extension
installation/upgrade anymore.

The patch reverts the changes to the original behaviour, so that a
follow-up patch can introduce the following behaviour:
- Install extension
- Do _safe_ DB updates for the whole system
- Do breaking DB updates for the extensions to be installed/upgraded
- Execute ext_tables_*adt.sql files + imports

Resolves: #85215
