conhost: Reimplement font dialog handling.
Much of the existing font dialog code is overly complicated and difficult
to follow. There are also bugs in the code, which cannot be fixed with
minimal changes due to the complexity of the existing source. For example,
changing the font face via the listbox unexpectedly changes the font size.
It is also unnecessary to recreate the list of available font sizes
each font face selection if the font type remains unchanged.
