* Remove all pointer-overflow suppressions from our UBSAN builds/tests.
* Add `ZSTD_ALLOW_POINTER_OVERFLOW_ATTR` macro to suppress
pointer-overflow at a per-function level. This is a superior approach
because it also applies to users who build zstd with UBSAN.
* Add `ZSTD_wrappedPtr{Diff,Add,Sub}()` that use these suppressions.
The end goal is to only tag these functions with
`ZSTD_ALLOW_POINTER_OVERFLOW`. But we can start by annoting functions
that rely on pointer overflow, and gradually transition to using
these.
* Add `ZSTD_maybeNullPtrAdd()` to simplify pointer addition when the
pointer may be `NULL`.
* Fix all the fuzzer issues that came up. I'm sure there will be a lot
more, but these are the ones that came up within a few minutes of
running the fuzzers, and while running GitHub CI.
