For #77131

This reverts commit 544b0abf.

For #81574

This applies the fix from #84878 to a number of other descriptor classes in our codebase

For #81574

See #84669 for details of the problem around strict function types. This change converts `SyncActionDescriptor` to use a static `create` function. This allows us to make the `create` function generic so that it can take the correct types for strictFunctionTypes

Our code currently uses the `IConstructorSignature` types in a two main ways:

- As argument types in functions that take a service constructor.
- As return types or property types when we expose a service constructor in the API

This first usage is not valid with strict function types. The reason is that the `IConstructorSignature` types takes a rest array of `...services: BrandedService[]` , while the concrete constructors you pass in use actual services. With strict function types, you cannot convert the concrete constructor type to an `IConstructorSignature` because this would drop important type information that the implementation needs. As an example

```ts
class Foo {
    constructor(@ILogService service: ILogService) {}
}

registerFoo(Foo);

// The type of `ctor` inlines `IConstructorSignature0`
function registerFoo(ctor: { new(....serivces: BrandedService[]): Foo}) {
   // When registerFoo(Foo) is called, the implementation here would need to know that
   // ctor needs to be invoked with exactly one `ILogService`. However the type of `IConstructorSignature0`
   // does not express this. Strict function types therefore disallows this conversion
}
```

To fix this, I have converted a few places were we were taking `IConstructorSignature` arguments so that they preserve the full type of the constructor. This fixed over half of our 900 strict function type errors. Unfortunatly I can not figure out a more elegant way to express this besides inlining the types

However, even after this change, we still need to figure out how to deal with:

- Places in the code where `IConstructorSignature` is exposed as a return type or object property
- How to deal with all of our descriptor types (such as `SyncActionDescriptor`)
