net: posix: fix hostname config conflict with unique updates

Decouple NET_HOSTNAME_MAX_LEN from NET_HOSTNAME_DYNAMIC to resolve
Kconfig conflict when using POSIX networking with unique hostname
updates. This restores functionality that worked in Zephyr 3.6.

- Remove forced selection of NET_HOSTNAME_DYNAMIC from POSIX_NETWORKING
- Make NET_HOSTNAME_MAX_LEN available independently
- Add build assertions for hostname length validation
- Update test configurations for new dependency structure

Fixes #95811
