winedbg: Print parameter values in backtraces in hex.

[Dmitry Timoshkov]

This patch makes it much easier to match values in a relay log with
values printed in a backtrace, as well as helping to match values of
many symbolic constants like win32 window styles, messages and many
more since they are defined in hex in header files.
