Plugin Framework bridge cross tests

[VenelinMartinov]

This is a test-only PR - it adds cross-tests for Diff for the plugin framework for the existing behaviour.

Each test defines a set of schemas and a set of scenarios and the full matrix of schemas X scenarios is run in cross-tests. For each of these test cases both pulumi and TF are run with the initial input then a preview is run with the second set of inputs and the outcome of the preview is compared.

We also record the stdout for both pulumi and TF for manual comparison of the preview output. The recordings also contain the inputs in order to make spot-checking them easier.

The full test plan is available in https://github.com/pulumi/pulumi-terraform-bridge/issues/2597
