Add brcmaudiodecoder detection hook in DeepElementAdded

[Copilot]

Adds detection for brcmaudiodecoder elements when audio decoder is assigned, providing an extension point for platform-specific handling.

Changes

• DeepElementAdded.cpp: Check element name prefix after m_curAudioDecoder assignment
• Follows existing pattern used for brcmaudiosink, amlhalasink in SetupElement.cpp
• Includes TODO placeholder for future decoder-specific configuration

// Check if audio decoder element name starts with brcmaudiodecoder
if (m_glibWrapper->gStrHasPrefix(GST_ELEMENT_NAME(m_element), "brcmaudiodecoder"))
{
    RIALTO_SERVER_LOG_DEBUG("brcmaudiodecoder detected: %s", m_elementName);
    // TODO: Add brcmaudiodecoder-specific code here
}
