[C-Target] Tracing: Provide a way for the user to enable/disable System Tracing

[mkhubaibumer]

Currently when tracing is turned "ON" the trace file becomes huge. There are times when the user only wants to enable custom/user-defined traces and the system needs to run for a long time. In such cases we need to provide a way for the user to Disable System Tracing

User can now specify system-trace option with:

target C {
    tracing: {
        trace-file-name:"sometrace",
        system-trace: false,
    },
    fast: true
}

User can now specify system-trace option with:

target C {
    tracing: {
        trace-file-name:"sometrace",
        system-trace: false,
    },
    fast: true
}

Hi @mkhubaibumer, there does not appear to be a PR that adds the system-trace option to the tracing target property. Did you forget to file it?
