AVRO-3722: [Ruby] Eagerly initialize instance variables for better inline cache
hits (#2132)
Eagerly initialize the `@type_adapter` instance variable to `nil` to see better
inline cache hits
> Eagerly Initialize Instance Variables in Ruby Implementation

> Key: AVRO-3722
> URL: https://issues.apache.org/jira/browse/AVRO-3722
> Project: Apache Avro
> Issue Type: Improvement
> Components: ruby

> Reporter: Aaron Patterson
> Priority: Trivial
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Ruby 3.2 introduced an inline cache scheme based on the "shape" of an object.
> The object's shape depends on what instance variables were set on the object
> and in what order. Lazily initializing an instance variable can cause poor
> inline cache performance because the order in which the IV is set may not be
> predictable.
> The Ruby version of Avro has an IV that is lazily initialized, and I would
> like to eagerly initialize it so that we can improve cache performance.
