feat: import.meta.filename and import.meta.dirname (#22061)

This commit adds `import.meta.filename` and `import.meta.dirname` APIs.

These APIs return string representation of filename and containing
dirname.
They are only defined for local modules (modules that have `file:///`
scheme).

Example:

```ts
console.log(import.meta.filename, import.meta.dirname)
```

Unix:
```
$ deno run /dev/my_module.ts
/dev/my_module.ts /dev/
```

Windows:
```
$ deno run C:\dev\my_module.ts
C:\dev\my_module.ts C:\
```
