[Internal] Migrate Share Resource to Plugin Framework

[rauchy]

Changes

This PR migrates the share resource to the Plugin framework. The code was largely copied "as is" from the previous implementation of the share resource, with the necessary adaptations made for integration with the Plugin framework.

This implementation utilizes the newly generated Effective fields to provide the functionality that was previously achieved through diff suppression.

Tests

• [x] make test run locally
• [ ] relevant change in docs/ folder
• [x] covered with integration tests in internal/acceptance
• [x] relevant acceptance tests are passing
• [x] using Go SDK

Thanks @renaudhartert-db for the review! Most of the issues are inherited from the migrated code, but no reason not to tidy up now :) Appreciate the comments.
