  [libpas] Add PAS_ALLOW_UNSAFE_BUFFER_USAGE macro to fix build
https://bugs.webkit.org/show_bug.cgi?id=285937
rdar://142905646

Reviewed by Geoffrey Garen.

After recent changes, the compiler is more aggressive
about `unsafe pointer arithmetic [-Werror,-Wunsafe-buffer-usage]`.

We should a macro similar to `WTF_ALLOW_UNSAFE_BUFFER_USAGE` to allow
libpas builds to continue for now, with a followup patch fixing these after.
