inlay parameter hint does not work for dependent function templates

Environment

• OS and version: Ubuntu 20.04
• VS Code: 1.70.0
• C/C++ extension: 1.20.0
• Other extensions you installed (and if the issue persists after disabling them):
• If using SSH remote, specify OS of remote machine:
• A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc).

Bug Summary and Steps to Reproduce

Bug Summary:
I'm not quite sure this should be a bug or a feature request, since it seems to be highly related with #2973

Steps to reproduce:

template <typename T>
void func1 (T arg);

template <typename T>
void func2 () {
    T val;
    func1(val);  // no inlay hint for `val`
    func1<int>(42);  // OK
}

Expected behavior

an inlay hint arg: appears before val, because there's no other overload besides the main template.

Code sample and Logs

template <typename T>
void func1 (T arg);

template <typename T>
void func2 () {
    T val;
    func1(val);  // no inlay hint for `val`
    func1<int>(42);  // OK
}

Inizia riproducendo l'esempio di template di funzione dipendente dell'issue con la VS Code C/C++ extension e conferma che la chiamata con template esplicito riceva un suggerimento inline, mentre la chiamata dedotta non lo riceva. Il lavoro è completato quando la chiamata dedotta visualizza un suggerimento arg: prima di val senza modificare il comportamento della chiamata con template esplicito.
