Update some functions

Here are list of changes:
- Added IP/subnet validation using Python's `ipaddress` module
- Added workaround for network configuration modes where user can enter DHCP or IP without brackets.
- Returned local printing options for some functions to keep `The above list...`
- Moved booleans for `generic_select` below options and text parameters
- Imported some functions from `archinstall` to reduce the`archinstall.` part of the lines.
- Reduced variable name length for simplicity
- Fixed some typos
