`A1-1-1`: Implementation of Rule only looks for deprecated features and not use of implementation extensions

[rcseacord]

Describe the bug Implementation of Rule A1-1-1 only looks for deprecated features and not use of implementation extensions

Expected behavior

// __try // Non-compliant - __try is a part of Visual Studio extension
try // Compliant - try keyword is a part of C++ Language Standard
