<Sound Dev> [9] Review Request: 8167028 SunCodec.java can be removed

[Sergey Bylokhov]

Hello, Audio Guru.

This is a request to small cleanup of the classes related to 
FormatConversionProvider.
  - SunCodec.java is removed. It was used as a parent class for other 
providers, but it contained only the methods to clone the array of 
supported formats. But we can have the same functionality if instead of 
cloning the array just create the new one each time it will be requested.
  - All our providers supports the same encodings as input and output. 
So getTargetEncodings() can be implemented via getSourceEncodings();
  - FormatConversionProvider contains a few methods to filter, search 
the data in arrays, and this functionality can be simplified by Stream API.

No regressions were found by jtreg/jck tests.
