This sets the query params to the list of param_view, which can be empty.
An empty list of params is distinct from having no params.
Reserved characters in the string are percent-escaped in the result.
assert( url( "http://example.com" ).set_params( {"id", "42"} ).query() == "id=42" );
this->has_query() == true
Strong guarantee. Calls to allocate may throw.
Linear.
query = *( pchar / "/" / "?" )
query-param = key [ "=" value ]
query-params = [ query-param ] *( "&" query-param )
