VSE: Display sound sample rate and channels

Display information about sound media in "Source" category in side panel
similar to movie resolution and framerate.

The specs are stored in the `Sequence` struct, and are extracted at
the moment of struct creation. If the "source file" is changed,
the specs change also.
