Chris H-C 8a65ae0861 Bug 1673660 - Move FOG C++ and JS API scaffolding headers to subdir r=janerik
Headers we want our consumers to use remain in mozilla/glean,
but scaffolding now lives in mozilla/glean/bindings.

This will allow me to have a binding for the GleanPings global in GleanPings.h
AS WELL AS a GleanPings.h which is the C++ consumer API for custom pings.
