lib/media_fill: Create common media_fill library for all gens

Let's create common media_fill library, similarly as for gpgpu_fill.
This will allow to make code easier to read and maintain.
Moreover we can create generic __gen9_media_fillfunc for future gens.
>From gen9 media fillfunctions differ only with kernel parameter.

v2: fixed indentations in files
v3: Added missing copyright headers. Made __gen9_media_fillfunc static.
Removed gen9 kernel (the same as for gen8).
v4: rebase
