Run TypeScript scripts directly

Also removes enums. There's --experimental-transform-types for that but that's still experimental and TS team regretted adding enums after all.

Fixes #2321
Closes #2125

This isn't really true 😄

I can't properly review this at the moment but should be able to do so in a few days

[jakebailey]

We should really just move these to src tbh

That's not strictly needed here and can happen separately IMO

[jakebailey]

Fair enough

That's what I'm told in some decades old issue, are things changed?

[jakebailey]

I'd just use an as const object and the keyof typeof trick

[saschanaz]

Hmmmmmmmmmmmmmmmm..................... I kinda prefer this way as it's simpler and it's what we do in web APIs 🤔

[jakebailey]

Sure, but this was a TS enum before, so IMO this is easier:

const EmitScope = {
    StaticOnly: "StaticOnly",
    InstanceOnly: "InstanceOnly",
    All: "All",
} as const;
type EmitScope = typeof EmitScope[keyof typeof EmitScope];

Then no other code has to change.

But, the strings aren't the worst either

[jakebailey]

We should set these to match https://nodejs.org/api/typescript.html#type-stripping

[jakebailey]

We'll probably want to set the options listed in https://nodejs.org/api/typescript.html#type-stripping

This PR seems fine to me, just has conflicts with main
