The gn build doesn't support xray, so there's no reason to make the xray
headers available. Some CMake checks check if xray includes are
available to determine if xray is usable. Since we don't build the xray
runtime, there are link errors.

This header fragment is useful on its own for any consumer that wants
to use custom instruction profile runtime with the LLVM instrumentation.
The concrete use case is in Fuchsia's kernel where we want to use
instruction profile instrumentation, but we cannot use the compiler-rt
runtime because it's not designed for use in the kernel environment.
This change allows installing this header as part of compiler-rt.

It hasn't seen active development in years, and it hasn't reached a
state where it was useful.
Remove the code until someone is interested in working on it again.

The Android sanitizer tests are currently some of the most difficult
to run correctly, requiring at least 3 build directories which have
to be configured in just the right way and built in the correct order
(see e.g. [1] and the functions that it calls).
This patch adds a check-hwasan target which greatly simplifies running
the hwasan tests for gn users, taking advantage of its support for
multiple toolchains. With this the tests can be run simply by setting
an NDK path and running "ninja check-hwasan" with a compatible Android
device connected. The Linux/x86_64 and Android/aarch64 targets are
tested in parallel.
