…, root) (elastic#204977)

## Summary
This PR is a pre-requisite for adding aggregation by process name and by
thread name to the Universal Profiling flamegraph view.

It adds three artificial node types to the flamegraph including color
codes.

As a side-effect, the root node now has its own color code. Previously,
it (accidentally) used the color code of "unknown" type frames.

The PR is backwards compatible, so it doesn't change anything in the UI
when connecting with current Elasticsearch.
As soon as [the PR for
ES](elastic/elasticsearch#119115) is merged, the
new aggregations show up.

…pe is root (#209978)

Closes elastic/prodfiler#4386

### Summary

The flyout for the root block always contains the hint "Missing symbols
error" because there are no symbols for the root block. We should not
show it here.

### What was done

Added a condition to not render the callout when frameType is root

Adds a type and color for `Executable` flamegraph nodes.

The new type will be used by [this

profiling plugin (the required code change from grouping by process name
to grouping by executable name needs tbd).
