Add support for GDB Catchpoints

Feature Request

While it is possible to set breakpoints in VS Code within a GDB debugging session, it is not possible to set catchpoints for e.g. syscalls from the GUI. Using the debug console it is possible with e.g. -exec catch syscall read but the Extension does not seem to recognize the catchpoints properly, since the following message is displayed, when hitting a catchpoint

It would be good to add a handling for catchpoints which is similar to breakpoints into the extension.
Possible features are:

• Option to add catchpoints from the "Breakpoints" Section in the "Run and Debug" panel. Alternatively, a Catchpoints section could be added below breakpoints
• Display what catchpoint has been hit in the editor

With kind regards

L’issue non indica file né test; inizia tracciando la gestione esistente dei breakpoint nell’estensione e il modo in cui vengono interpretati gli eventi di arresto di GDB. Confronta la creazione e la visualizzazione richieste dei catchpoint con il comportamento attuale dei breakpoint. Il lavoro è completato quando i catchpoint possono essere aggiunti dalla Run and Debug UI e un catchpoint raggiunto viene riconosciuto e mostrato.
