blockchain/vm: vmLog/feePayer/validateSender precompiled contract address mapping

[yoomee1313]

Proposed changes

• vmLog/feePayer/validateSender precompiled contracts' address will be changed after the istanbulCompatible change. You can see how the address changes by looking at the yellow highlights in the table below.
  

• However, the vmLog/feePayer/validateSender calling functions that are already in use cannot be used after the change. By this PR, we can still use those functions by utilizing CodeFormat. It is used as an incompatible change version.

• Originally, when a smart contract is released, CodeFormatEVM is assigned to that contract. By this PR, CodeFormatEVM2 is assigned to the new contracts which will be deployed after istanbulCompatible change.

• The result below shows the success result of calling precompiled contract according to those conditions: node's incompatible change version (constantinople/istanbul), deployment time, and call time. before means a contract is deployed or called before the IstanbulCompatible change. after means a contract is deployed or called after the IstanbulCompatible change.

@yoomee1313 I don't understand why Istanbul Address is callable when deployment time is Before and call time is After. I think calling Istanbul Address of the contact may not be intended by the contract author.

I don't understand why Istanbul Address is callable when deployment time is Before and call time is After.

I never thought deeply about what I pointed out. Thank you. I checked how geth handled it, and the Istanbul address is callable when the contract is deployed before the istanbul change. Unfortunately, I couldn't find the reason or related documentation about this.

I think calling Istanbul Address of the contact may not be intended by the contract author.

Since this is a new item address, it will not be the case that the author did not intend.
