Adds Conan-based packaging/build support for SOCI (upgraded to 4.1.4) and iODBC, and refactors the SQL extension to consume these dependencies via new CMake “source” selectors.

Changes:

• Introduce Conan recipes + conandata/config for SOCI 4.1.4 and iODBC 3.52.16 (including portability patches).
• Refactor extensions/sql to use GetSOCI / GetIODBC instead of inline ExternalProject_Add.
• Add new build options for selecting BUILD vs CONAN sources, and add enable_sql to the root Conan options/bootstrapping.
