The ansi_term crate is unmaintained, resulting in a RUSTSEC advisory that we must ignore.

Look for maintained alternatives, once they're ready, as suggested in the linked ansi_term issue.

Update clap to remove suppressions (#2856)
cd18c60 
A Friday afternoon jaunt.

To be merged after #2855; does the remaining work to close #2277 (and closes off some things that Dependabot was trying to upgrade).

Tested by manually running the commands; we don't have good coverage for this kind of stuff. OTOH, most of these commands are for the experimental local fuzzing mode, which is not fully supported yet. I did specifically test the `onefuzz-task managed` command which is the one used in production.

## Details

- Bump `clap` to 4.1.6
  - Remove `structopt` as this is subsumed by clap now
- Bump `envlogger` to 0.10 (removes problematic dependency)
- Set `default-features=false` on `proc-maps` (removes a feature which is only needed to support FreeBSD), and bump it to 0.3

The main changes migrating `clap` are:

- `value_t!` is gone; now use `matches.get_one::<T>`. If `T` is not `String` then a parser must have been registered on the `Arg` when it was created, with `arg.value_parser(value_parser!(T))`.
- `Command::with_name` and `Arg::with_name` are now called `new`.
- `Command` and `Subcommand` were unified, and `App` is removed.
- `arg.takes_value(true)` is gone; it is the default. For flags use `arg.action(ArgAction::SetTrue)` and then retrieve the flag value with `matches.get_flag`.

This code would be simplified a lot by using the `clap::Parser` on structs, but that requires reworking the code significantly as we cannot dynamically add/remove arguments the way that this is currently done.

## Also found

Found one bug while manually testing the `onefuzz-task local` commands; see comment below.
