Isolated declarations emit is different from TSC

[escaton]

Given

export class Boo {
  constructor(
    public readonly prop: number = 0,
    private readonly prop2: number = 1,
    readonly prop3: number = 1,
  ) {}
}

Oxc generates:

export declare class Boo {
	readonly prop: number;
	private readonly prop2: number;
	readonly prop3: number;
	constructor(prop?: number, prop2?: number, prop3?: number);
}

TSC:

export declare class Boo {
    readonly prop: number;
    private readonly prop2;
    readonly prop3: number;
    constructor(prop?: number, prop2?: number, prop3?: number);
}

If param.accessibility is private we can give type_annotation as None

Lines 234 to 242 in 78c66d3

	if param.accessibility.is_some() {
	// transformed params will definitely have type annotation
	let type_annotation = self.ast.copy(&params.items[index].pattern.type_annotation);
	if let Some(new_element) =
	self.transform_formal_parameter_to_class_property(param, type_annotation)
	{
	elements.push(new_element);
