cargo-tree: Add no-proc-macro to edges flag

[XAMPPRocky]

Describe the problem you are trying to solve

We're trying evaluate what dependencies are ending up in the final binary of a program, cargo-tree -e normal gets us most of the way there, however normal still includes proc-macros and their dependencies, which are only run on the host machine and don't end up in the final target binary, proc-macros usually have a lot of dependencies so the list given by tree is cluttered, and requires manual filtering to get the final list of dependencies. It would be nice if there was an option to only see dependencies which will be compiled to the target platform.

Describe the solution you'd like

Add -e no-proc-macro edge to remove all dependencies that are currently marked as a proc-macro and their sub-dependencies.
