feat: add support for Geth built-in tracers

[Wodann]

This PR removes our custom EIP-3155 tracer and instead uses revm-inspector's DebugInspector. This brings us one step closer to unification of the tracing architecture, as we can use the same underlying inspector to generate our stack traces.

During testing, I discovered a bug in revm-inspectors. I was able to fix the bug and created a PR. After some back and forth, I'm waiting for the final approval. Until then, I decided to go ahead with a temporary dependency patch, using my fork of revm-inspectors. If desired, I can move the fork to the NomicFoundation organisation.

The hardhat-tests are using fixtures to validate that the generated output of debug_traceCall and debug_traceTransaction matches what Geth returns for specific requests. Unfortunately, the fixtures were old and no longer reflect the behaviour of the latest version of Geth. As such, I had to update the fixtures.

For future reference, I added instructions for how to generate new fixtures for future versions of Geth to each individual fixture. The instructions slightly differ per fixture as each fixture contains different JSON-RPC requests.

For fixtures that use "forking mode" I could not use Geth, since Geth does not support the concept of forking a blockchain. It can only fully sync to the live blockchain. To avoid a lot of time and storage to sync a node, I generated fixtures for "forking mode" by calling Alchemy. As Alchemy runs a mixture of clients (e.g. Erigon, Reth, and Geth), this does run a risk of hitting an Archive node that generates its JSON-RPC responses using Reth, which uses the same alloy dependency as us. I deemed this to be an acceptable trade-off to save a lot of time.

There is one outstanding issue. A previously disabled test can theoretically be re-enabled. However, I discovered a bug in REVM. I fixed the bug and created a PR. Once that's merged, I'll upgrade REVM and re-activate the test in a follow-up PR.

Lint error should be resolved by #1255

[Wodann]

Motivation: To ensure that the stack trace tests keep succeeding, we need to add new solc compiler descriptions up until the version of Solidity that EDR reports as supporting.
