Andrew Kaster 4a5a1e8648 Userland: Port UBSAN implementation to userspace
Take Kernel/UBSanitizer.cpp and make a copy in LibSanitizer.

We can use LibSanitizer to hold other sanitizers as people implement
them :^).

To enable UBSAN for LibC, DynamicLoader, and other low level system
libraries, LibUBSanitizer is built as a serenity_libc, and has a static
version for LibCStatic to use. The approach is the same as that taken in

Note that this means now UBSAN is enabled for code generators, Lagom,
Kernel, and Userspace with -DENABLE_UNDEFINED_SANTIZER=ON. In userspace
however, UBSAN is not deadly (yet).
