feat: Start warning on each use of a deprecated API (#21939) This commit introduces deprecation warnings for "Deno.*" APIs. This is gonna be quite noisy, but should tremendously help with user code updates to ensure smooth migration to Deno 2.0. The warning is printed at each unique call site to help quickly identify where code needs to be adjusted. There's some stack frame filtering going on to remove frames that are not useful to the user and would only cause confusion. The warning can be silenced using "--quiet" flag or "DENO_NO_DEPRECATION_WARNINGS" env var. "Deno.run()" API is now using this warning. Other deprecated APIs will start warning in follow up PRs. Example: ```js import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts"; const p = Deno.run({ cmd: [ Deno.execPath(), "eval", "console.log('hello world')", ], }); await p.status(); p.close(); async function runEcho() { const p = Deno.run({ cmd: [ Deno.execPath(), "eval", "console.log('hello world')", ], }); await p.status(); p.close(); } await runEcho(); await runEcho(); for (let i = 0; i < 10; i++) { await runEcho(); } await runEcho2(); ``` ``` $ deno run --allow-read foo.js Warning ├ Use of deprecated "Deno.run()" API. │ ├ This API will be removed in Deno 2.0.
