This enables `allowDeclareFields` flag that allows code like:
```ts
class Foo {
declare prop: string;
}
```
Declaring is a workaround for inheritance vs property initialization
issues.

For `allowDeclareFields` to work, we have to run
plugin-transform-typescript before plugin-proposal-class-properties and
few others, so this change migrates from preset-typescript that always
runs last to individual plugin-transform-typescript, and reorders some
plugins.
