chore(core/rawdb): use libevm core/rawdb

[qdm12]

Why this should be merged

Gets rid of most of core/rawdb geth code using libevm.

You might want to review the PR commit by commit, given historically, work for this PR was done as:

• First stage (see commits) was to get code as close to geth code (libevm main branch) as possible.
• Second stage was identifying the differences: ReadBlock's use of extras and InspectDatabase
• Third stage was implement libevm hooks and other change and use libevm core/rawdb (last commit)

How this works

• Move our own code to _ext.go files
• Import symbols from libevm in imports.go
• Use Block and Body hooks previously implemented

How this was tested

CI passing

Need to be documented?

No

Need to update RELEASES.md?
