perf stat: Implement --topdown using json metrics
Request the topdown metric group of a level with the metrics in the
group 'TopdownL<level>' rather than through specific events. As more
topdown levels are supported this way, such as 6 on Intel Ice Lake,
default to just showing the level 1 metrics. This can be overridden
using '--td-level'. Rather than determine the maximum topdown level
from sysfs, use the metric group names. Remove some now unused topdown
code.
