[wpimath, wpiutil]: Specify that java_multiple_files is true in Protobuf files and regenerate

Closes #8256

For the aid of other reviewers, I could run the below commands in zsh on 75d0211 without any output from git diff:

% git restore --source $(git merge-base 2027 HEAD) -- $(find wpimath/src -type f -path '*/java/*' -not -path '*/generated/*')
% sed -e 's/^\(import .*proto\.\)[^.]*\.\(Protobuf[a-zA-Z0-9]*;\)/\1\2/' -i .old $(find wpimath/src -type f)
% git diff

(% is the command prompt)

This should probably also set the outer class name, since that's what the original issue was about. Probably want to call it something like Protobuf<name>Descriptor to differentiate from the other classes (both the normal classes and the other protobuf classes).

the outer class name of the .java generated files, or the .proto files themselves?

[Gold856]

The Java generated files. I really don’t want to see protobuf_name_descriptor.h in includes.

[Gold856]

Use option java_outer_classname in the .proto file to rename the classes. You'll have to use a name other than a Protobuf prefix because of the name conflict with ProtobufTrajectory. Protobuf<Name>Descriptor is probably fine. Also, resolve all merge conflicts.

ok this PR is kinda broken again 😭 on to v3 I guess. thanks a lot #8468

You'll need to delete the old generated Java protobuf files (e.g., proto/Spline.java, proto/ProtobufController.java, proto/ProtobufPlant.java, etc.). The pregenerate CI failing also suggests you'll need to regenerate quickbuf and nanopb because of the changes to how linear system is organized.
The easiest approach will probably be to delete all of the generated Java protobuf files and then rerun wpimath/generate_quickbuf.py. You'll need to rerun wpimath/generate_quickbuf.py anyways, and deleting every file is simpler/easier than selectively deleting around a dozen files. (In the VSCode file tree, just click the first file in the directory, shift + click the last file (every file should be selected), and press delete.)
