feat: annotation processor codegen configuration

[lauzadis]

• Adds a skeleton for supporting codegen configuration of the annotation processor. One config field GenerateBuilderClasses is added with options of WHEN_REQUIRED (default) or ALWAYS. When set to WHEN_REQUIRED, the annotation processor will not generate builder classes if they are not necessary.
• Adds support for generating schemas for classes annotated with @DynamoDbSortKey
• Disable the plugin test package until the plugin can be applied correctly
