feat: Remove entrypoint collection (#2148)

Attempt at removing the horrifying `EntrypointCollection` class. This
allows us to remove the `{ sender: address }` option when sending a tx,
and instead just rely on the `Wallet` attached to the Contract instance
to decide which sender to use. In other words, there is now only one way
to choose which account sends a tx, following ethers conventions, rather
than web3js. It also allows us to clean up some utils that are no longer
necessary.
