vim, vim-core: upgraded packages to upstream

Upgraded app-editors/vim to version 8.2.4586 on amd64, arm64
Upgraded app-editors/vim-core to version 8.2.4586 on amd64, arm64

Used command:

```
cros_portage_upgrade --upgrade --unstable-ok --board=lakitu:lakitu-arm64 app-editors/vim app-editors/vim-core
```

Modifications done after running the above command:
 - The above command installs python-utils-r1 in portage-stable/eclass which differs from python-utils-r1 we use from eclass-overlay/eclass. Therefore, removed the eclass from portage-stable.
 - Updated the PYTHON_COMPAT in the ebuild to {6..9} from {7..10}
