LibWeb: Change Resource's m_encoding to Optional<String>

Browse source 
This modifies the Resource class to use Optional<String> for the
encoding. If the encoding is unknown, the Optional will not have a
value (instead of using the null state of the String class). It also
implements a has_encoding() instance method and modifies the callers
of Resource::encoding() to use the new API.
