System clock timestamps should only come from a single source:
util::timestamp_ns(). Externally, this function is exposed as
roctracer_get_timestamp() (used by the tracer tool).
Removed the now unused HSA Runtime Utilities which were never part
of the ROCtracer API.

A trace buffer is used to efficiently store synchronous event records
so that they can be processed later, possibly in a different thread,
when the buffer is flushed. This helps reduce the latency added by
tracing API calls.
The API does not need to use trace buffers as synchronous events are
directly reported to the client with callbacks, and asynchronous events
(activities) are saved in memory pools.
The implentation of HSA asynchronous memory copy activities was using
a trace buffer shared with the tracer tool to write the records to a
file (async_copy_trace.txt), instead of using a memory pool and
reporting the activity to the client.
Removed the asynchronous memory copies trace buffer, and updated
hsa_async_copy_handler to use the pool specified when the activity
was enabled.
Updated the tracer tool to read HSA_OP_ID_COPY records out of the
default memory pool and write them to async_copy_trace.txt.
Move trace_buffer.h to test/tool as tracer_tool.cpp is now the only
file using it.

The HCC runtime is no longer used, so move all the remaining
activities in the HipApi loader and remove the HccLoader.

Move roctracer_cb_table.h to the src/core directory, as it should not
be exposed as a public header, and rename it callback_table.h

roctracer_status_t roctracer_get_timestamp(uint64_t* timestamp);
Get system timestamp for roctracer clients.
The API could be used to help roctracer clients understand the reference frame
of timestamps when receiving activity callbacks, as the nanoseconds reported in
the activity callbacks are not in the same reference frame as CPU walltime
clock.
