Akira Hatanaka f6b06b42a3 [PAC] Implement function pointer re-signing (#98847) ...

Re-signing occurs when function type discrimination is enabled and a
function pointer is converted to another function pointer type that
requires signing using a different discriminator. A function pointer is
re-signed using discriminator zero when it's converted to a pointer to a
non-function type such as `void*`.
