chore!: remove memsize (#155)

## Why this should be merged

`memsize` blocks usage of Go 1.23. We'll be building with 1.23 via
`avalanchego` anyway (which doesn't transitively import `memsize`) so we
want to run tests with the correct version. It will also unblock #154.

## How this works

✂️ 

We already cherry-pick the upstream commit
(e4675771ed) that removes `memsize` when
on release branches so we instead do it ourselves and no longer
cherry-pick. To avoid conflicts at the next `geth` sync, this PR should
be reverted before performing the merge. See #128.

## How this was tested

Existing tests.
