perf annotate: Add support to toggle percent type



Add new key bindings to toggle percent type/base in annotation UI browser:

 'p' to switch between local and global percent type
 'b' to switch between hits and perdio percent base

Add the following help messages to the UI browser '?' window:

  ...
  p             Toggle percent type [local/global]
  b             Toggle percent base [period/hits]
  ...
