Enhance Codec Iteration and Checking of HardwareConfigMethodFlags (#40)

Browse Source 
* Add IterateCodecs, Add codec.HasHardwareConfigMethodFlag

* Remove HasHardwareConfigMethodFlag test because git worklow does not support hw

HasHardwareConfigMethodFlag is tested on my local device but does not work in git

* Review Changes

Remove unused arg in HardwareConfigs
Add mehtod to get all codecs
Update test

* Remove codecporcessor type
