To maximize the cpu utilization, core 0 is usually shared by service
vm and guest vm. But there are no statistics to show the cpu occupation
of each vm.
This patch is to provide cpu usage statistic for users. To calculate
it, a new trace event is added and marked in scheduling context switch,
accompanying with a new python script to analyze the data from acrntrace
output.

Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

Now ACRN support platform which CPU numbers are large than 10. So the old value
for DEV_PATH_LEN is not enough (18 is not enough for /dev/acrn_trace_xx).

While we hoped to make the headings consistent over time while doing
other edits, we should instead just make the squirrels happy and do them
all at once or they'll likely never be made consistent.
A python script was used to find the headings, and then a call to
https://pypi.org/project/titlecase to transform the title. A visual
inspection was used to tweak a few unexpected resulting titles.
