feat: add filtering options to provisioners list (#19378)

## Summary

In this pull request we're adding support for additional filtering
options to the `provisioners list` CLI command and the
`/provisionerdaemons` API endpoint.

Resolves: https://github.com/coder/coder/issues/18783

### Changes

#### Added CLI Options

- `--show-offline`: When this option is provided, all provisioner
daemons will be returned. This means that when `--show-offline` is not
provided only `idle` and `busy` provisioner daemons will be returned.
- `--status=<list_of_statuses>`: When this option is provided with a
comma-separated list of valid statuses (`idle`, `busy`, or `offline`)
only provisioner daemons that have these statuses will be returned.
- `--max-age=<duration>`: When this option is provided with a valid
duration value (e.g., `24h`, `30s`) only provisioner daemons with a
`last_seen_at` timestamp within the provided max age will be returned.

#### Query Params

- `?offline=true`: Include offline provisioner daemons in the results.
Offline provisioner daemons will be excluded if `?offline=false` or if
offline is not provided.
- `?status=<list_of_statuses>`: Include provisioner daemons with the
specified statuses.
- `?max_age=<duration>`: Include provisioner daemons with a
`last_seen_at` timestamp within the max age duration.

#### Frontend

- Since offline provisioners will not be returned by default anymore
(`--show-offline` has to be provided to see them), a checkbox was added
to the provisioners list page to allow for offline provisioners to be
displayed
- A revamp of the provisioners page will be done in:
https://github.com/coder/coder/issues/17156, this checkbox change was
just added to maintain currently functionality with the backend updates

### Show Offline vs Offline Status

To list offline provisioner daemons, users can either:

1. Include the `--show-offline` option

OR

2. Include `offline` in the list of values provided to the `--status`
option
