[Chromoting] Use compact notation for javascript @private types

[Chromoting] Use compact notation for javascript @private types

This is a mechanical change to replace single- and multi-line:
  @type {type} @private
with single-line:
  @private {type}

No functional changes in this cl - just updating the jscompiler annotations to make the code easier to read.
