Optimize query for product page

[michenly]

Description

Part of Shopify/hydrogen#778

What was done:

• remove most of the hinted fields that was potentially over fetching. (But kept video related fields to account for the variety of all the media types even though there is no videos media file in the demo shop.)
• inline all query variables that is not passed into useShopQuery
• order most of the fields and remove duplicated fields

I think line 62 has a duplicate id that could be removed.

Also, do you mind removing as many variables as you can as well? Since these queries aren't dynamic anymore, there's no point in having those variables there I don't think.

@frehner so inline all the variables as well?

In addition to removing variables, where did we land on rewriting the metafields to the new specific metafield version?

[michenly]

@jplhomer , @frehner mentioned that we are keeping the deprecated metafield fields till 2022-07 API version

@frehner so inline all the variables as well?

As many as you can. I think the country variable should remain, but most everything else can be inlined. See https://github.com/Shopify/hydrogen/pull/919/files as a reference if that helps.
