[Survey] Update XML schema validation structure

[abrahammordev]

This PR fixes an issue detected in Testrail test T85968 and reported in Mantis 47144.

When importing a Survey Question Pool, the import could fail during XML schema validation of the LOM metadata export. The failing package contained a rights element where the schema expected the mandatory general element first.

Changes

• Add component-level LOM initialization for Survey objects (svy).
• Add component-level LOM initialization for Survey Question Pool objects (spl).
• Register the corresponding setup migrations in the Survey and Survey Question Pool setup agents.
• Fix the Survey Question Pool export dependencies so the common ILIAS object data is included correctly.
