Add support to test that a schema written in framework is equivalent to one written in SDK

[remyleone]

Module version

github.com/hashicorp/terraform-plugin-framework v1.16.1

Use-cases

As a maintainer of a provider written in SDKv2, I would like when I migrate a ressource to verify that the schema I have written in framework is equivalent to one written in SDK.

That would be very helpful to ensure that no customers is going to update to a broken schema.

Attempted Solutions

Manually check field by field.
Using the acceptance testing that is already in place.

Proposal

Could you add to the framework a list of function that would check that a resource / data source schema are indeed compatible between the SDKv2 and the framework.

It would be helpful to add any tooling existing to do this task to the following documentation page:
