[refactor]: Optimize executor

[Arjentix]

Description

Originally this work was about #3991. But after implementing reference counting for ConstString I got these results:

1. 7.5 - 13 % less memory footprint
2. 50 - 75 % slower

I measured memory using the next command:

gtime -f 'Time passed: %E\nMax memory used: %M kbytes' ../../target/release/examples/apply_blocks

Where gtime is a time utility by GNU, which can be installed on mac using brew install gnu-time

So it defenelty doesn't worth it.

You can do your own research. Take a look at my branch: https://github.com/arjentix/iroha/tree/arc_name

• Fixed apply_blocks benchmark
• Made apply_blocks even more heavy with long ids
• After that this benchmarks just stops woring on iroha2-dev, the issue was a very long transaction deallocation inside wasm executor, so fixed that with core::mem::forget()
• Some minor refactoring

Benefits
