chore: ensure libevm new files wrap errors with appropriate context

[qdm12]

Rationale

We should be able to quickly find where an error is coming from, and have a minimal context on what failed. To do so we can:

• use fmt.Errorf("doing this: %s", err) to wrap errors coming from 'below' layers
• use fmt.Errorf("failed this: some details context") when creating an error, with necessary details

⚠️ careful geth is not checking the error directly with == instead of errors.Is otherwise it means we cannot add error context wrapping.

Implementation

Check all *libevm* files as well as geth original source files that were modified for:

• regex return.+err and add wrapping if appropriate
• check other return statements in case we return the error directly without wrapping i.e. return f() where f returns an error

ℹ️ Note we obviously don't want to modify parts we did not add on top of geth and that we did not modify in geth original code
