Complete support for no_entry and no_exit turn restrictions (#5988)

Browse Source 
The internal representation of turn restrictions expects only one
`from` way and only one `to` way.

`no_entry` and `no_exit` turn restrictions can have multiple `from` and
`to` ways respectively. This means they are not fully supported by
OSRM's restriction parser.

We complete support for these turn restriction types by parsing all
ways and converting a valid restriction with multiple `from`/`to` members
into multiple internal restrictions.
