[EVM] Add feature flag for deploying EVM contract only with ABI functionality

[m-Peter]

Adds the relevant config options and contract code, for deploying the EVM contract with only the necessary functionality for ABI encoding/decoding:

• EVM.encodeABI
• EVM.decodeABI
• EVM.encodeABIWithSignature
• EVM.decodeABIWithSignature

The EVM.EVMAddress type is also included in the minified EVM contract, as it is required for encoding/decoding to the Solidity address type.

Nice!

Given this is just a feature flag and the value is only used in Go / not passed to Cadence, this can just be a plain bool (and usages below as well)

Suggested change

	evmAbiOnly cadence.Bool
	evmAbiOnly bool

[m-Peter]

Yeah, I was wondering about it as well, but it seems that every config is a Cadence value. Not sure why.

The code looks good to me, though I recommend waiting for the setup fixes by @janezpodhostnik to be merged first and then we merge this PR.
