fix(workers): Don't panic when a worker's parent thread stops running (#12156) This panic could happen in the following cases: - A non-fatal error being thrown from a worker, that doesn't terminate the worker's execution, but propagates to the main thread without being handled, and makes the main thread terminate. - A nested worker being alive while its parent worker gets terminated. - A race condition if the main event loop terminates the worker as part of its last task, but the worker doesn't fully terminate before the main event loop stops running. This panic happens because a worker's event loop should have pending ops as long as the worker isn't closed or terminated – but if an event loop finishes running while it has living workers, its associated `WorkerThread` structs will be dropped, closing the channels that keep those ops pending. This change adds a `Drop` implementation to `WorkerThread`, which terminates the worker without waiting for a response. This fixes the panic, and makes it so nested workers are automatically terminated once any of their ancestors is closed or terminated. This change also refactors a worker's termination code into a `WorkerThread::terminate()` method. Closes #11342. Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>

refactor: rename InternalModuleLoader to ExtModuleLoader, use ext: scheme for snapshotted modules (#18041) This commit renames "deno_core::InternalModuleLoader" to "ExtModuleLoader" and changes the specifiers used by the modules loaded from this loader to "ext:". "internal:" scheme was really ambiguous and it's more characters than "ext:", which should result in slightly smaller snapshot size. Closes https://github.com/denoland/deno/issues/18020

refactor(core): limit number of boundary crossings between Rust and V8 (#18652) This commit refactors "deno_core" to do fewer boundary crossings from Rust to V8. In other words we are now calling V8 from Rust fewer times. This is done by merging 3 distinct callbacks into a single one. Instead of having "op resolve" callback, "next tick" callback and "macrotask queue" callback, we now have only "Deno.core.eventLoopTick" callback, which is responsible for doing the same actions previous 3 callbacks. On each of the event loop we were doing at least 2 boundary crosses (timers macrotask queue callback and unhandled promise rejection callback) and up to 4 crosses if there were op response and next tick callbacks coming from Node.js compatibility layer. Now this is all done in a single callback. Closes https://github.com/denoland/deno/issues/18620
