`ZeroCopyBuf` was convenient to use, but sometimes it did hide details that some copies were necessary in certain cases. Also it made it way to easy for the caller to pass around and convert into different values. This commit splits `ZeroCopyBuf` into `JsBuffer` (an array buffer coming from V8) and `ToJsBuffer` (a Rust buffer that will be converted into a V8 array buffer). As a result some magical conversions were removed (they were never used) limiting the API surface and preparing for changes in #19534. |

Deno Core Crate
The main dependency of this crate is rusty_v8, which provides the V8-Rust bindings.
This Rust crate contains the essential V8 bindings for Deno's command-line interface (Deno CLI). The main abstraction here is the JsRuntime which provides a way to execute JavaScript.
The JsRuntime implements an event loop abstraction for the executed code that
keeps track of all pending tasks (async ops, dynamic module loads). It is user's
responsibility to drive that loop by using JsRuntime::run_event_loop method -
it must be executed in the context of Rust's future executor (eg. tokio, smol).
Rust functions can be registered in JavaScript using deno_core::Extension. Use
the Deno.core.ops.op_name() and Deno.core.opAsync("op_name", ...) functions
to trigger the op function callback. A conventional way to write ops is using
the deno_ops crate.
Documentation for this crate is thin at the moment. Please see hello_world.rs and http_bench_json_ops/main.rs as examples of usage.
TypeScript support and lots of other functionality are not available at this layer. See the CLI for that.
