Add support for IN list padding in SQL queries

[nakamura-to]

This pull request adds a feature to pad IN clause parameters to the nearest power of two, which improves SQL caching.

This feature is available for SQL templates and the Criteria APIs but is not supported in query builders from the org.seasar.doma.jdbc.builder package.

To enable it, create a SqlBuilderSettings implementation where requiresInListPadding returns true, and return this implementation from the getSqlBuilderSettings method in your Config implementation.

SqlBuilderSettings implementation

class MySqlBuilderSettings implements SqlBuilderSettings {
   @Override
   public boolean requiresInListPadding() {
    return true;
  }
}

Config implementation

class AppConfig implements Config {
  private final SqlBuilderSettings sqlBuilderSettings = new MySqlBuilderSettings();

   @Override
   public SqlBuilderSettings getSqlBuilderSettings() {
    return sqlBuilderSettings;
  }
}

This feature is equivalent to jOOQ's IN-list padding and Hibernate's in_clause_parameter_padding.
