The merchant domain url is only required in case of samsung pay payments on web. While processing payments on app the merchant domain is not required. Hence mandate the merchant domain only if the `x-client-platform` is `web`

<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
