[Tizen][extension] Add AVCodecs support in device capabilities

The main idea is as follows:
Utilize the API <code>IsSupportedMediaMimeType</code>, <code>IsSupportedStrictMediaMimeType</code>, <code>AreSupportedMediaCodecs</code> in <code>src/net/base/mime_util.h</code> to iterate the local codecs sets <code>audio_codecs</code> and <code>video_codecs</code> which we maintain to check if the current codec is supported. If true, the codec will be added in the supported media codecs list. The checking logic will refer <code>WebMimeRegistry</code>’s <code>supportsMediaMIMEType</code> function.
