[refactor] #3833, #2373, #3601: Split off Kagami

[0x009922]

Description

Outline:

• Refactor Kagami
  • Remove kagami validator
  • Remove kagami swarm
  • Refactor kagami genesis according to the comment
• Introduce iroha_swarm: according to the comment
• Introduce iroha_wasm_builder_cli: a CLI around iroha_wasm_builder. It replaces kagami validator in the following way:

  # before
  kagami validator > validator.wasm
  
  # after
  iroha_wasm_builder_cli check ./default_validator
  iroha_wasm_builder_cli build ./default_validator --optimize --format > validator.wasm

• Update CI scripts which used the previous commands

Linked issue

Closes #3833 #2373 #3601

Benefits

• Kagami is now a portable and lightweight tool. There is no issue with mentioning it in the documentation.
• Swarm is now simpler, without redundant functionality. Easy to enhance in the future.
• A general tool for building smartcontracts. Easy to enhance in the future. More reliable than kagami validator thanks to spinners.

Checklist

• Investigate the logic behind the format option in iroha_wasm_builder::Builder, maybe open an issue to refactor it.
• Self-review
• Add README to iroha_swarm

Good to feel the old crutches gone. Overall structure is much more digestible too.
