[roll] Roll fuchsia [roll] Roll llvm-project/libc [libc] Implement sys/personality.h (#195065)
Added the personality() syscall wrapper, which sets or queries the
process execution domain. The function signature follows the Linux man
page: int personality(unsigned long persona).
New files:
* libc/include/sys/personality.{yaml,h.def}
* libc/src/sys/personality/ (implementation + linux/ syscall)
* libc/test/src/sys/personality/ (unit tests)
Registered the entrypoint and header for x86_64, aarch64, riscv, and
arm. The implementation includes <linux/personality.h> for the
kernel-defined constants (PER_LINUX, ADDR_NO_RANDOMIZE, etc.) following
the same pattern as sys/prctl.h.
