Change exceptions.h functions to use gdb::function_view
This changes some functions in exceptions.h to use gdb::function_view,
then fixes up the fallout. This lead to some surprising places, like
a function pointer in target_so_ops.
While writing this I found that catch_exception_ftype was unused, so I
removed this.
Note that I did not compile the windows-nat.c change, so I don't know
if it works.
Regression tested by the buildbot.
