Marco Elver 6a0ef7326e kcsan: Instrument memcpy/memset/memmove with newer Clang

commit 7c201739beef1a586d806463f1465429cdce34c5 upstream.

With Clang version 16+, -fsanitize=thread will turn
memcpy/memset/memmove calls in instrumented functions into
__tsan_memcpy/__tsan_memset/__tsan_memmove calls respectively.

Add these functions to the core KCSAN runtime, so that we (a) catch data
races with mem* functions, and (b) won't run into linker errors with
such newer compilers.
