VcFormat setting C_Cpp.vcFormat.indent.lambdaBracesWhenParameter:true not respected when lambda has non trivial capture

Bug type: Language Service

Describe the bug

If a lambda used as a parameter to a function has a capture list with an non trivial assignment, [q = p + 1], the lambda body is not indented properly. "C_Cpp.vcFormat.indent.lambdaBracesWhenParameter": true is the default value, so it is expected that parameter lambdas have their bodies indented.

• OS and Version: Ubuntu 18.04.6
• VS Code Version: 1.61.2
• C/C++ Extension Version:1.7.1
• Other extensions you installed (and if the issue persists after disabling them): all other extensions are disabled

Steps to reproduce

1. Ensure vcFormat is the cpp formatter
2. format code in the sample below

Expected behavior

parameter lambdas that have non trivial capture lists should be indented relative to the function in which they are a parameter

Code sample and logs

#include <future>

void test()
{
    int q = 1;
    int p = 8;

    std::async(
        [q]() mutable
        {
            // indented
        });

    std::async(
        [q = p + 1]()
    {
        // not indented
    });
}

By the way there is a similar (opposite?) bug in visual studio, not sure if it's relevant:

Beginne mit dem bereitgestellten C++-Beispiel und der auf vcFormat konfigurierten Einstellung C_Cpp.formatting und vergleiche dann die Formatierung für einfache und nicht-triviale Lambda-Captures. Als erledigt gilt die Aufgabe, wenn Parameter-Lambdas mit nicht-trivialen Capture-Listen ihre Bodies relativ zur umgebenden Funktion eingerückt haben.
