"if" braces deindentation problem (same as Issue #30933) happens with the C/C++ extension

[FredericChasse]

I have observed the same behavior as #30933, but for the C/C++ extension.

• VSCode Version: 1.52.0
• OS Version: Windows_NT x64 10.0.19041

Steps to Reproduce:

In a C or C++ source file, type "if (cond)":

if (cond) |

Press enter:

if (cond)
    |

Type {, then enter. Expected:

if (cond)
{
    |
}

Actual:

if (cond)
    {
    |
    }

Does this issue occur when all extensions are disabled?: No. It is specifically the C/C++ extension
