Directly test bedrock v0 encoding and hashing against legacy implementations

[maurelian]

Description

Although it may seem obvious, we were not directly testing that Bedrock's V0 hashing and encoding schemes match those of the legacy system.

Tests

Two tests:

1. testFuzz_encodeCrossDomainMessage_matchesLegacy_succeeds
2. testFuzz_hashCrossDomainMessageV0_matchesLegacy_succeeds

Perhaps there is non determinism with weth9 because its pulling in the weth9 from the legacy contracts repo?

[tynes]

If this causes build issues by pulling in the dep, I recommend we just copy/paste the function in with a comment including a hyperlink to the git commit that it was copy pasted from, since we are going to delete the contracts package eventually
