LOG: [PAC][libc++] Fix build with `ptrauth_calls` feature (#211033)

After partial revert of #208330 in #209928, the libcxx build started
failing because of missing `<cstdint>` include required for `uintptr_t`
declaration used only by code behind `ptrauth_calls` feature check. See
https://lab.llvm.org/buildbot/#/builders/227/builds/3358

This patch adds the missing include.

(cherry picked from commit 12e1c7f70f34d59c023d05d0fe2c228a4e9aac11)

Added: 
    

Modified:
