Remove CDM_5

Remove CDM_5 Support

As we never shipped a CDM based on CDM_5, we can remove the code.
CDM_4 will be removed later, once all clients are upgraded to CDM_6.

BUG=401815
TEST=existing EME tests still pass

Since this is not contiguous which is unusual, add a comment that Host_5 is not
supported. We can remove that comment after Host_4 support is dropped.
