Port of #29746
Fixes #29985
Description
In EF7, processing seed data in the model snapshot could result in an incorrect provider type when the property has a converter. This change ports a fix already in EF8 to ensure provider types are used correctly.
Customer impact
Many customers reporting that models with seed data will continually update this data on every migration, even though the data never changes. This means every generated migration contains Up and Down steps, even when the migration should be empty. No reasonable workaround.
How found
Multiple customer reports on 7.0.
Regression
Yes.
Testing
New tests added for this kind of seed data in the model snapshot.
Risk
Medium. Significant code changes, but these changes have been in the 8.0 code for several months now, and they are quirked here.
