Revert support for long to int type demotion

Summary

Revert support for long to int type demotion introduced in #590 , #591 and #593 .

All modified files were reverted except for following files:

helper/impls/helper-impl-19/src/main/java/com/linkedin/avroutil1/compatibility/avro19/codec/ResolvingDecoder.java
helper/impls/helper-impl-110/src/main/java/com/linkedin/avroutil1/compatibility/avro110/codec/ResolvingDecoder.java
helper/impls/helper-impl-111/src/main/java/com/linkedin/avroutil1/compatibility/avro111/codec/ResolvingDecoder.java

In those I reverted almost everything except for "implements CustomDecoder" in class definitions because it is referenced in SpecificDatumReaderExt classes.

Any new files that were introduced in those PRs were kept and newly introduced java classes were marked as deprecated.

Details

First two versions (Avro 1.4 and 1.5) I reverted manually, then used copilot to revert the remaining versions. Later I found that I missed some things in manual commits, I didn't realize avro 1.4 and 1.5 files were touched in the last two PRs as well. I used copilot to verify that everything was reverted. Here is the summary:
