related to substrait-io/substrait#940 and substrait-io/substrait#849

• updates the substrait submodule to 0.81.0
• removes core/src/main/java/io/substrait/type/proto/ParameterizedProtoConverter.java which is no longer part of the spec
• removes core/src/main/java/io/substrait/type/proto/TypeExpressionProtoVisitor.java which is no longer part of the spec

I'm in support of this, but let's wait until the upstream is resolved before merging this IMO.

EDIT: Also, when the upstream settles, we will have to bump the version of substait here, and then this file will become a compilation error :)

Fine with me. Just found this file in my research to understand whether this is used anywhere and thought I prepare the PR before I forget about it.

Nice, thanks for doing this! I don't know if this is the best place to raise this discussion, but I'm wondering if we should try and make a point moving forwards of opening tickets for all of the relevant upstream substrait changes so that we don't forget to tackle them.

This is not relevant for this PR because

1. it is already merged, and
2. the only relevant change is something I have already made a ticket for here

Just making a note for the future! Thanks 🚀

I created a thread in the Substrait Slack in #substrait-java.
