[DA] Planetscale engine tests: occ

[miguelff]

This is a subcluster of failures after having enabled planetscale tests in https://github.com/prisma/prisma-engines/pull/4423

Failing tests in this cluster:

new::occ::occ::occ_delete_test
new::occ::occ::occ_update_many_test
new::occ::occ::occ_update_test

Please follow this process

Is this potentially related to https://github.com/prisma/prisma/issues/21867?

I confirm that this is related to https://github.com/prisma/prisma/issues/21867.

If our PlanetScale drivers were set up to be using relationMode = "foreignKeys" in the query-engine test suite, the OCC test cases above would pass with both the Vitess("planetscale.js") (Napi) and the Vitess("planetscale.js.wasm") (Wasm) test tags:

test new::occ::occ::occ_update_many_test ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 1667 filtered out; finished in 4.68s

test new::occ::occ::occ_delete_test ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 1667 filtered out; finished in 1.93s

test new::occ::occ::occ_update_test ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 1667 filtered out; finished in 1.84s

I'd recommend a refactoring of the connector-test-kit-rs test suite setup to allow opting in and out of relationMode = "prisma" | "foreignKeys", so that we can consistently run CI on e.g. OCC tests with PlanetScale. The specifics of this technical change can be discussed with other engineers in the team.
