[wpimath] Commit generated quickbuf Java files (#5994)

This removes a build dependency on the quickbuf generator being available for the build platform.

It's safe to generate Java because the quickbuf version is defined by the project.

C++ protobufs can't be committed because the protoc version must
match the library version (this is a particular issue for cmake builds).
