  Suppress function pointer type validation in clang ubsan

We've been concerned about ubsan errors comming with more recent
versions of clang.  specifically versions of clang later than 17
generate hundreds of function pointer type validation errors, i.e.
assigning a function of type void (*)(TYPE *) to a function pointer of
type void (*)(void *).

Fixing these requires the creation of lots of thunk function that get
littered through the code base, and are generally unpleasant to carry.
A better fix requires siginficant code refactoring, and potentially
large changes to our ABI, which we can't support until the next major
release.

So, for now, just suppress those ubsan errors, so we can more properly
deal with the issue when we are able.
