DRIVERS-2888 Support QE with Client.bulkWrite

[mdb-ad]

Add spec test for client bulkWrite QE.

C driver implementation

libmongocrypt requirement: 1.10
Drivers changes required:

• QE unified test support (DRIVERS-3106)
• bulkWrite specific changes: don't error on QE bulkWrite. Implement batch splitting.

Please complete the following before merging:

• Update changelog.
• Test changes in at least one language driver. (C driver)
• Test these changes against all server versions and topologies (including standalone, replica set, sharded
  clusters, and serverless). (Note: C driver doesn't currently test CSFLE with sharded)

I may be out of the loop on some of the context, are drivers changes needed to get these passing? Is there a specific libmongocrypt version needed?

There seems to be more unified test changes in the C driver than are here, are those just extra test sync(s) or are they new tests?

Suggest updating this PR description to give an overview of needed changes. I expect implementors will refer to this PR (and the C driver PR).

C driver implementation

Suggest linking to the C driver PR (once created) rather than the Evergreen patch. The patch appears to include unrelated spec tests.

@kevinAlbs @mdb-ad Is there any chance https://jira.mongodb.org/browse/DRIVERS-2859 can be completed before DRIVERS-2888? It makes much more sense to make the change in once place than making the changes in every driver. This is especially true because drivers supporting non-document sequences for client bulk write will be temporary until https://jira.mongodb.org/browse/DRIVERS-2859 is addressed. So making drivers implement the changes before https://jira.mongodb.org/browse/DRIVERS-2859 will cost extra work in every driver, extra work updating the spec to allow (or enforce) document sequences with bulk write after https://jira.mongodb.org/browse/DRIVERS-2859 is implemented, and then again extra work in drivers to support document sequencing for bulkWrite with QE.

From a more selfish, Node-specific perspective - our bulkWrite implementation is tightly coupled to document sequences and making this change might be non-trivial. I'd rather not refactor our bulk write implementation unless absolutely necessary.

The C driver only required a minor change to support QE with MongoClient.bulkWrite. Supporting CSFLE with MongoCollection.bulkWrite already requires passing all write documents in a non-document sequence, and the C driver reuses it.

I propose: proceed with this PR to unblock some drivers with QE, but add a blurb suggesting drivers wait for DRIVERS-2859:

Auto-Encryption

libmongocrypt does not-yet support OP_MSG document sequences (DRIVERS-2859). Drivers requiring significant changes to pass a bulkWrite command to libmongocrypt may prefer to wait until DRIVERS-2859 is implemented to support automatic encryption.

LGTM with the prose tests numbering restored.
