[Privacy Indicator] Option to ignore specific pipewire nodes

### Feature Description

I'd like to be able to select/filter out certain microphone-using pipewire nodes from lighting up the privacy indicator.

### Use Case

I use a pipewire's [RNNoise](https://github.com/xiph/rnnoise) filter-chain Since my microphone picks up basically anything happening in my room.
This is a seperate pipewire node that auto-hooks onto my microphone and replaces the default input device.

This makes the privacy indicator always show the microphone as being listened to:

coppwr graph for context:

pulseaudiocontrol for context:

### Compositor(s)

All compositors

### If Other, please specify

_No response_

### Proposed Solution

exclude-matching-pw-nodes:
key: [user provided node property key], value: [user provided node property value]

I think a single key, value pair to look for and match on suffices.
