This implements two macros to simplify extension registration and centralize a lot of the boilerplate as a base for future improvements: * `deno_core::ops!` registers a block of `#[op]`s, optionally with type parameters, useful for places where we share lists of ops * `deno_core::extension!` is used to register an extension, and creates two methods that can be used at runtime/snapshot generation time: `init_ops` and `init_ops_and_esm`. --------- Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>
