Covers adding the new JS global `GleanPings` for JS, the new structs for C++ at mozilla::glean_pings, ping-id and string-table-index codegen, the usual boilerplate for JS and C++ stuff, and tests. Unresolved: * What happens if we call this on a non-parent process? (This isn't a supported mode of operation) Differential Revision: https://phabricator.services.mozilla.com/D98671
