tx: rename method names (remove EIP word)

[jochem-brouwer]

This PR does one thing and that is to remove the EIP word from the Tx library methods and classes. (Also renames constructors as create7702EOACodeTx to createEOACode7702Tx)

I have only used "find-and-replace" so if CI passes this should be fine.

To quickly test the renames, build the library, and then in node require('@ethereumjs/tx') and verify the output names of the exported methods/classes.
