pipewire: add pw-voiceui SVA voice-UI control/listen client

Add the pw-voiceui tool, a CLI for controlling and monitoring the SVA
(Sound Trigger / Voice Activation) voice-UI PipeWire node exposed by
the pw-pal-plugin (media.role=VoiceUI). Supports list/info/listen,
setting SVA parameters, and sending commands.

Add 0003-tools-add-pw-voiceui-SVA-voice-UI-control-listen-cl.patch,
reference it from SRC_URI, and list pw-voiceui in FILES:${PN}-tools.

+Subject: [PATCH] tools: add pw-voiceui SVA voice-UI control/listen client
+
+Add a pw-voiceui command-line tool for interacting with the SVA
+(Sound Trigger / Voice Activation) voice-UI node exposed on the
+PipeWire graph by the pw-pal-plugin.
+
+The tool locates the target node by media.role=VoiceUI (or an
+explicit name/id), and supports:
+  - list / info: enumerate/describe the VoiceUI node
+  - set <sva-key> <value>: set a validated SVA property (confidence
+    level, sound model path, capture-requested, mode, lab settings,
+    sample rate/channels/bit width, reset, restart)
+  - set-param / send-command: send an arbitrary POD param or node
+    command, built from a JSON payload, for lower-level control
+  - listen: subscribe to the "sva.events" metadata object and print
+    sva.state updates (detection events) as they arrive
+
+src/tools/meson.build: register pw-voiceui as a built tool alongside
+the other pw-* utilities.
