Use fnv1a_hash_extend with config_hash and version for wifi preferences

Browse Source 
Change wifi component to use fnv1a_hash_extend(config_hash, ESPHOME_VERSION)
instead of fnv1_hash(compilation_time) for the preferences hash.

This ensures wifi settings are invalidated on config or version changes,
not just on recompilation.
