feat(iroh): Enable netwatch::netmon::Monitor and the metrics feature in Wasm (#3206)

## Description

- Enables the `netwatch` dependency in Wasm
- Un-cfg-s the `netwatch::netmon::Monitor` in `magicsock::Actor`
- Enables the `metrics` feature for Wasm by depending on a newer
iroh-metrics
- Minor: We go back to using `netwatch::ip::is_unicast_link_local`, as
we can depend on that in Wasm again now.

## Notes & open questions

There's some dependencies:
- [x] Needs #3203 to be merged first
- [x] Depends on n0-computer/net-tools#14 being
merged
- [x] And released
- [x] Depends on a new release of the `iroh-metrics` main branch (I.e.
n0-computer/iroh-metrics#11 being released)

Closes #3195

## Change checklist

- [x] Self-review.
