Add inlay hints to constructor calls

Feature Request

It would be nice if inlay hints were also shown for the parameter/member names in constructors:

Note how inlay hints are shown for the function, but not for the normal constructor call or the aggregate initialization.

struct with_constructor
{
	int a_;
	int b_;

	with_constructor(int a, int b) : a_{a}, b_{b} {}
};

struct aggregate
{
	int a;
	int b;
};

void method(int a, int b) {}

int main()
{
	with_constructor a(1, 2);
	with_constructor b{1, 2};
	aggregate c{1, 2};
	method(1, 2);
}

Start by examining the existing inlay-hint behavior for function calls in the vscode-cpptools repository, then compare it with the constructor and aggregate-initialization examples in this issue. Done means parameter or member-name hints appear for both constructor forms and aggregate initialization without regressing ordinary function-call hints.
