DRIVERS-2581 specify bindings benchmark

[kevinAlbs]

Summary

• Specify the benchmark: Benchmarking Bulk Decryption.

The benchmark has been implemented in the libmongocrypt Java bindings here with support for multiple threads in review here: https://github.com/mongodb/libmongocrypt/pull/700#pullrequestreview-1639948555:

Background & Motivation

Benchmarking helped to measure performance related changes to libmongocrypt and Java bindings in MONGOCRYPT-589 and MONGOCRYPT-595.

Specifying the benchmark is intended to help language teams implement DRIVERS-2581.

Seems like we're no longer going to implement DRIVERS-2581. Is it relevant as a justification for this work?

[kevinAlbs]

I plan to revise and DRIVERS-2581 to suggest language bindings projects add benchmarks and use the newly exported mongocrypt_binary_t definition to improve performance.
