make `enumsAsTypes` export a const of the values as well as the type

### Is your feature request related to a problem? Please describe.

If I want to use `enumsAsTypes` because I want the string union, I have no way to get the list of values of the string union. There are cases in which I want both the string union AND the list of all values in my enum. You _could_ use `enumsAsConsts`, but one could also want to use `enumsAsTypes` (for example, you might not like the weird capitalization things that happen with keys in the generated const).

This change seems pretty harmless - 99% backwards compatible (pending small questions) and adds to the existing feature.

Some questions for you:
- Should we do something better with naming? `MyEnumValues` or something? need to avoid collisions

### Describe the solution you'd like

When `enumsAsTypes` is true, I want there to be the following lines:

```
export const MyEnum = ['A', 'B'] as const;
export type MyEnum = typeof MyEnum[number];
```
