Environment-variable capability trait and error types.
Sync: env access is a single map lookup on both native (std::env) and
wasm (process.env).
set and unset are intentionally absent from this trait. libdatadog is
embedded in many kinds of runtime, where mutating the process environment
very much unsafe. Exposing mutation here would make it trivially easy for
callers to corrupt the environment of a multi-threaded host process.
