research: precompile call evm in the same session

To achieve true interoperability between native code(precompiles) and EVM, native code should be able to call EVM in the same EVM instance.

Precompiles can call the four variant of `evm.Call*` method to call evm contracts with the current evm instance, but there are a few issues to beware of:

* Context passing. Precompile should pass the current calling context down the stream.
* to do that, precompiles needs to receive the correct calling contexts first (https://github.com/cosmos/go-ethereum/pull/10).
* jumpDests cache need to be passed as well.

* Precompile implementations should deal with re-entrant calls.

Anything else? or is there projects that had did this before that we can take as reference?

## Use Cases

Any non-trivial precompile contract will need to be able to call back into EVM world back and force, for example a native DEX that works with ERC20 contracts.

Start by reviewing the four evm.Call* variants and the context-passing concerns described in the issue, including jumpDests cache handling and the referenced PR. Examine how precompile implementations would handle re-entrant calls. Done means documenting the remaining requirements, relevant prior projects, and a clear implementation direction for same-instance calls.
