feat: External Contexts and simple EvmBuilder

[rakita]

A lot of changes and Evm now contains just a Context and a Handler, context is divided into EvmContext and generic external context (Generic struct) and Handler contains a list of functions (handlers) that introduce logic.

EvmBuilder sets context and handler and allows creation of the Evm, where Evm is used in execution.

A few more handlers are added to Handler.

Precompile inner vec is replaced with HashSet as performance for 10 items is similar (the interesting thing is that linear search was faster than binary search for small numbers).
