code editing: correctly underlined but incorrectly explained out-of-class specifier

Environment

• OS and Version: Ubuntu 20.04.1
• VS Code Version: 1.81.1
• C/C++ Extension Version: 1.17.5
• If using SSH remote, specify OS of remote machine: (not using)

Bug Summary and Steps to Reproduce

Bug Summary: incorrectly described specifier problem

Steps to reproduce:

1. Write a function with a specifier that is only allowed inside class definition
2. The specifier should be underlined by cpp language tools
3. Observe the error.

Expected behavior: The error message should be "invalid specifier outside a class definition"

Reason: class (forward) declarations can not have specifiers inside/outside as they have no scope and don't use {}. Such specifiers can appear only inside class definition.
