Motivation

I'm working in a very restricted WASM environment (see #2532), which I can not use ethers-providers crate. However I would like to use ethers_contract::EthCall derive functions.

Solution

With this PR, I introduced the providers flag in ethers-contract, ethers-contract-abigen, and ethers-contract-derive. Anything related to ethers-providers is now enabled with the flag.

providers flag was added in the default features of ethers-contract.

If a user adds ethers or ethers-middleware crates, then providers is always enabled, even if user disabled the default flags. This is because they have ethers-providers as a dependency and there is no reason to make the flag optional.

If a user adds ethers-contract and disables default features, then they need to add providers feature to get the same functionality as before. - Is this edge case a major breaking change?

If you have any other ideas how this can be better, let me know.

The tests that are failing are not related to my changes and they failing before the changes on my machine.

I found that foundry was responsible for the test failures. The tests are passing with version nightly-e05b9c75b4501d5880764948b61db787f3dd7fe0 and they fail with version nightly-2d87c0c2fcc47088feecc72721c46d8e07e3c220

With the latest foundry nightly the tests passed, so this PR is ready. Any comments are welcome.
