hw: register vm session's vcpus as trace sources #5793
Description
Currently, you can observe strange execution times of threads when running x86 virtualization scenarios on top of base-hw. This is due to the fact that only threads and their execution times are collected when using the TRACE session via components like: top or top_view. If a vcpu is using a big share of the cpu time, it is invisible to these tools. Therefore, the relative cpu usage of the residual threads gets over-estimated.
To get appropriated values, and to see the cpu usage of the vcpu, those core objects need to be registered within the global trace source registry.
