Postgres v2: Add support for DeleteWithPrefix

[ItalyPaleAle]

Related to #3262

Adds DeleteWithPrefix to the PostgreSQL state store v2.

Notes:

1. This cannot work with CockroachDB, because CockroachDB does not offer sufficient support for UDFs which are needed to implement this. We will investigate how to add support for CockroachDB later. For now, the component can be instantiated without support for DeleteWithPrefix, so it can be used with CockroachDB
2. Because of lack of CockroachDB support, this has not been implemented in v1, due to the fact that the components for v1 are more "intertwined". Will be done in a separate PR.
3. Added conformance tests for YugabyteDB
   • Note that using YugabyteDB requires installing the "crypto" extension. See: https://yugabytedb.tips/?p=2178 We should investigate if we can have Dapr do that automatically.

Moving to draft to investigate how we can add support for YugabyteDB and CockroachDB.

CockroachDB 23 has some support for UDFs and should be usable.

However, neither YugabyteDB nor CockroachDB support the trim_array function, which we would like to use.

My attempt at defining another UDF "equivalent" to trim_array in CockroachDB failed, as CockroachDB cannot have a UDF invoke another UDF.

Enabling conformance tests for Yugabyte really should be a separate PR

Agree. I'll leave it here for now so I can test that the feature works with Yugabyte too, but I'll move it out before marking the PR as ready for review.
