Use `encryptedClient` to also drop state collections created for QE.
Testing with crypt_shared/mongocryptd 8.1+ and pre-8.1 server results in not matching QE fields in sub-pipelines. This is a known server limitation.

LGTM, though note above comment.
All relevant tests are now passing in the Java implementation mongodb/mongo-java-driver#1638

Summary
Add prose test for
$lookupsupport in QE/CSFLE.Tests were run in the C driver in this patch. Note:
latesttasks were updated to uselatest-buildto use unreleased 8.1 builds (see slack for background).Testing requires a unreleased version of libmongocrypt to include changes from MONGOCRYPT-723. Binaries are available on this patch build or by building from source at mongodb/libmongocrypt@33fdf65.
The failed
Markdown Link Checkon the GitHub action appears unrelated (and is failing on master).libmongocrypt protocol change
libmongocrypt's protocol previously assumed auto encrypting a command only required at most one schema. With
$lookupthere can be multiple schemas on anaggregatecommand. As a result, a small driver change is needed: feed all listCollections results to libmongocrypt in theMONGOCRYPT_CTX_NEED_MONGO_COLLINFO(_WITH_DB)states. The previous protocol only required returning the first. Callmongocrypt_setopt_enable_multiple_collinfoto indicate the new behavior is implemented (otherwise libmongocrypt returns an error if a command requires multiple schemas).The libmongocrypt documentation includes a change to the protocol in integrating.md.
See the small protocol change implemented in the C driver here.
