## 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.
