Move fastboot specific config to a meta tag; keep manifest in

package.json for broccoli-asset-rev support

This commit builds fastboot specific config (available via
FastBoot.config()) to meta tag, which will be extracted by fastboot
when served.

The fastboot config meta has the name ending with
"config/fastboot-environement" to distinguish from regular
"config/environement" meta tags. If the new meta tags are not found,
which happens in embroider builds, we fallback to find regular meta
tags.
