More efficient JSON codecs for sets and maps

[plokhotnyuk]

The smaller set or map the better speed up of JSON parsing and serialization.

Also, this commit improves the internal implementation of instantiations of encoders and decoders to reduce number of instances (by removing of redundant parameter for discriminator) and speed up their instantiation for complex schemas.

Below are throughput results before and after proposed changes for different lengths of sets and maps with Scala 3 and JDK 21 on Intel® Core™ i7-11800H CPU @ 2.3GHz (max 4.6GHz).
