GeocodeQuery WithBounds not strictly used across providers that support it

[mwargan]

The WithBounds logic needs to be added to providers, as the method is a base method in the query.

E.g. in Nominatims provider we see:

        $viewbox = $query->getData('viewbox');
        if (!is_null($viewbox) && is_array($viewbox) && 4 === count($viewbox)) {
            $url .= '&'.http_build_query([
                'viewbox' => implode(',', $viewbox),
            ], '', '&', PHP_QUERY_RFC3986);

            $bounded = $query->getData('bounded');
            if (!is_null($bounded) && true === $bounded) {
                $url .= '&'.http_build_query([
                    'bounded' => 1,
                ], '', '&', PHP_QUERY_RFC3986);
            }
        }

The above should instead or in-addition accept $query->getBounds(), because otherwise it forces us to write code like:

        // Bounds of EU/UK where our customers are
        $euBounds = new Bounds(34.857764, -30.428009, 75.400203, 41.642303);

        $geocodeQuery = GeocodeQuery::create($query)
            ->withBounds($euBounds)
            // For Nominatim
            ->withData('viewbox', $euBounds->toArray());

Pelias Providers and those that extend it don't support it at all -even though Pelias does:
https://github.com/pelias/documentation/blob/master/search.md#search-within-a-rectangular-region

    /**
     * @param array<string, mixed> $query_data additional query data (API key for instance)
     *
     * @throws \Geocoder\Exception\Exception
     */
    protected function getGeocodeQueryUrl(GeocodeQuery $query, array $query_data = []): string
    {
        $address = $query->getText();

        // This API doesn't handle IPs
        if (filter_var($address, FILTER_VALIDATE_IP)) {
            throw new UnsupportedOperation(sprintf('The %s provider does not support IP addresses, only street addresses.', $this->getName()));
        }

        $data = [
            'text' => $address,
            'size' => $query->getLimit(),
            'layers' => null !== $query->getData('layers') ? implode(',', $query->getData('layers')) : null,
            'boundary.country' => null !== $query->getData('boundary.country') ? implode(',', $query->getData('boundary.country')) : null,
        ];

        return sprintf('%s/search?%s', $this->root, http_build_query(array_merge($data, $query_data)));
    }
