pw_bluetooth: Replace pw::Vector with pw::span on input parameters

When passing a struct with a set of parameters such as the
LocalServerInfo or AdvertisingData, use a pw::span<const T> instead of a
pw::Vector<T>. The latter can't be directly constructed unless a variant
with a fixed maximum size is used.

Fixed some spelling typos.
