Add a helper method to SConscript.main for adding .pdb files to the

output target of .exe files on Windows.  Change all the callers to
only pass in the basename of the target (e.g., 'base_unittests').
The only exception is chrome.exe which uses chrome_exe.pdb.

This lets us remove a "if env['PLATFORM'] == 'win32'" condition from
base/SConscript and these other files going forward.
