Add context menu to left-click on item in symbol statistics list.

The context menu contains two items:

1. "View symbol", which shows the symbol code / disassembly. This was
   previously available by right-clicking on the source file name.
2. "Sample entry call stacks", which brings up the list window that
   was previously available with left-click on the entry line.

This change intends to make the symbol view easier to discover.
