VPAAMP-474 [AAMP][Xione-Dhruv]- CC fails to resume after midroll ad when user performs Play/Pause actions during ad playback

[cpc005]

Also VPAAMP-187 [RDKE][Xione UK][VOD]Subtitles not displayed after enabling un-skippable ads
Reason for change: In InterfacePlayerRDK::SetupStream() an attempt is made to unmute the subtitles before gstreamer has configured the pipeline. The unmute gets lost.

• Delay setting of the unmute until state changes to PLAY.
• Do not mute subtitles just because PlayerCCManger::Init() is called

Pull request overview

This PR aims to fix closed captions/subtitle resume issues (VPAAMP-474) by deferring subtitle unmute until the GStreamer pipeline is confirmed ready (PLAYING), avoiding an early unmute that can be lost during pipeline setup.

Changes:

• Introduces setSubtitlePending to defer subtitle unmute until the pipeline reaches PLAYING.
• Updates bus state-change handling to apply the deferred subtitle unmute.

InterfacePlayerRDK.cpp:4524

• The deferred subtitle logic only applies an unmute when subtitleMuted is false. If subtitleMuted is true (default), the sink’s mute property is never applied once the pipeline becomes ready, so subtitles may render even though subtitleMuted indicates they should be muted; additionally setSubtitlePending is never cleared in that case.

Apply the pending subtitle mute state (true/false) once PLAYING is reached and clear the pending flag unconditionally.

				if (privatePlayer->gstPrivateContext->subtitle_sink && privatePlayer->gstPrivateContext->setSubtitlePending && !privatePlayer->gstPrivateContext->subtitleMuted)
				{
					pInterfacePlayerRDK->SetSubtitleMute(false);
					privatePlayer->gstPrivateContext->setSubtitlePending = false;
				}
