  [MLIR] emitc: Add emitc.file op (#123298)

A `emitc.file` represents a file that can be emitted
into a single C++ file.

This allows to manage multiple source files within the same MLIR module,
but emit them into separate files.

This feature is opt-in.
By default, `mlir-translate` emits all ops outside of `emitc.file`
and ignores all `emitc.file` ops and their bodies.

When specifying the `-file-id=id` flag,
`mlir-translate` emits all ops outside of `emitc.file` and
the ops within the `emitc.file` with matching `id`.

Example:

```mlir
emitc.file "main" {
  func @func_one() {
    return
  }
}
emitc.file "test" {
  func @func_two() {
   return
  }
}
```

`mlir-translate -file-id=main` will emit `func_one` and
`mlir-translate -file-id=test` will emit `func_two`.
