aleth-precompiles library

[gumb0]

Fixes https://github.com/ethereum/aleth/issues/5788

This replaces the precompiles infrastructure with the new EVMC module library.

Information about which revision activates each precompile for now is still in ChainParams class.

Option to build as a shared library is not added yet.

What was the blocker on this? Lack of time / lack of usefulness?

Rather lack of usefulness.

But this PR is ready from my side except evmc_create_aleth_precompiles naming problem mentioned above.
