Add kebab menu item in tor logs to copy all logs

Summary

Summarize the bug encountered concisely.

As mentioned in the #41187 Figma designs (screenshot below), we should have a kebab menu item in the top right of the tor logs screen, with a drop down to "Copy logs".

This is non-trivial in android since the base settings item would need to be changed and properly implemented.
