Automatically expand the call tree to show the search string

From [Bug 1341906](https://bugzilla.mozilla.org/show_bug.cgi?id=1341906):

> Ehsan often posts profiles like https://perfht.ml/2kNMh2B with some filter pre-selected. It would be a lot more convenient if whole path expanded to that filter string, instead I have to guess in which branch the search term probably is and manually expand the path.

┆Issue is synchronized with this [Jira Task](https://mozilla-hub.atlassian.net/browse/FP-105)

Reproduce the issue using a profile with a pre-selected search filter, then inspect the call tree behavior and the path containing the search string. Done means the complete path to the matching filter string is expanded automatically instead of requiring manual branch expansion.
