Enhance EVM Test Suite

[gator-boi]

I reviewed the ethereum directory. The tests in this PR are meant to replicate the existing javascript tests. However, these tests need a lot of work and there should be a follow up PR that fixes these tests (and adds a more comprehensive test suite). Here is a short list of enhancements we could add to improve the test suite:

• Splitting out tests into positive and negative tests. Currently, a lot of the revert statements are triggered in the same test that evaluate happy path logic.
• Changing the test names (and add a comment for each test describing what the test does). Some of the test names are insanely long and are difficult to read.
• Adding helper functions for payload generation. For example, the Bridge tests could use a method that generates a token transfer payload given some common inputs.
• Write helper functions to set up certain testing scenarios rather than calling other tests internally.
• Use the wormhole interfaces in the tests instead of duplicating events, and constants.
• Fuzz testing

Resolved the comments in #4070, but I expect that all of them should be addressed along with this issue as @gator-boi described.
