This is clever! I'm excited to see how these pieces fit together in Servo!

This allows us to use realm in place of cx without calling any methods as compiler will deref automatically. Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

Main usages of using global JSContext in servo are from realms, so with this PR we introduce safe realm concepts that are derived from JSContext (this allows us to enforce LIFO of realms). We also introduce counterpart to servos
AlreadyInRealmandInRealm: https://github.com/servo/servo/blob/main/components/script_bindings/realms.rs. Eventually these new safe types should replace old servo types. Because this change make it hard to use runtime I removed most methods from it.
