The documentation for trace events says that every subdirectory which
has trace events should have a trace.h header, whose only content is
an include of the trace/trace-<subdir>.h file.

When we added the trace events in target/arm/hvf/ we forgot to create
this file and instead hvf.c directly includes
trace/trace-target_arm_hvf.h.

Create the standard trace.h file to bring this into line with the
convention.
