This adds support for `fish_trace`, a new variable intended to serve the same purpose as `set -x` as in bash. Setting this variable to anything non-empty causes execution to be traced. In the future we may give more specific meaning to the value of the variable. The user's prompt is not traced unless you run it explicitly. Events are also not traced because it is noisy; however autoloading is. Fixes #3427
