[Bug]: emitDecoratorMetadata not respected in Deno Deploy

### Problem description

While `experimentalDecorators` setting in deno.json is now respected since https://github.com/denoland/deno/pull/22521
`emitDecoratorMetadata` is not. Unlike the former issue, it doesn't seem to be an issue with `deno compile`. In fact, compiled deno apps work as expected locally.

This issue makes decorator-based dependency injection not viable in deno apps in Deploy.

### Steps to reproduce

### `deno.json`
```json
{
"compilerOptions": {
"experimentalDecorators": true,
"emitDecoratorMetadata": true
}
}
```

### `server.ts`
```ts
import { Reflect } from 'https://deno.land/x/deno_reflect@v0.2.1/mod.ts';

export type ClassConstructor = new (...args: any[]) => T;

function Annotation() {
return (_: ClassConstructor): void => {};
}

class Custom {

}

@Annotation()
class Test {
constructor(name: string, age: number, custom : Custom) {}
}

Deno.serve((_request: Request) => {
const metadata = Reflect.getMetadata('design:paramtypes', Test);

return new Response(metadata?.map((x: ClassConstructor) => x.name).join(', ') || 'No metadata. But it should output "String, Number, Custom"');
});
```

### Expected behavior

Classes annotated with TC39 decorators should emit metadata that should be made available in `design:paramtypes`.

### Environment

### works in this environment
deno 1.41.1 (release, x86_64-apple-darwin)
v8 12.1.285.27
typescript 5.3.3

### doesn't work in
Deno Deploy (as of March 10th 2024)

### Possible solution

_No response_

### Additional context

_No response_

Start by deploying the provided deno.json and server.ts reproduction to Deno Deploy and compare it with the stated working local environment. Confirm whether design:paramtypes metadata is absent for Test; done means the deployed response reports String, Number, Custom as expected.
