v7.5.2 breaks `protobuf.Type.encode` and `protobuf.Type.create` methods

[alvarowolfx]

After release of version v7.5.2, our unit and system tests on Node BigQuery Storage library started to fail. I tested with multiple versions and it works just fine from 7.2.4 to 7.5.1 and fails with 7.5.2. Sounds like this PR might be causing the issue: #2068

I saw @sofisl trying to revert this PR on https://github.com/protobufjs/protobuf.js/compare/revert-2068-resolve-fix, but no release was cut with that. There is any plans to rollback this behavior ? I'm still investigating how to fix in the protobuf lib. It seems to be parsing the proto descriptor correct as a Type, but when trying to encode into a protobuf binary, it fails.

More repro scenarios can be seen in the bigquery storage repo: https://github.com/googleapis/nodejs-bigquery-storage/blob/21122f5901fd5b6670c4a3271045a9b3828b7f6b/test/adapt/proto.ts#L198

minimal repro extracted from the BigQuery Node library:
