If we want to load the u_trace output somewhere for analysis it's much
easier to deal with json than to parse strings.

With the Iris driver, the first tracepoint triggers the tracepoint for
"begin of command buffer" which leads to 2 tracepoints using the same
idx.

When using the Vulkan API, command buffers can be recorded way before
perfetto is enabled. This can be problematic if you want already
recorded command buffers to produce traces.
This new environment variable makes perfetto enabled internally so
that command buffers are recorded with timestamps, even though no
perfetto recording happens.

In order to capture the timestamp when things actually end on Intel
GPU HW, we need to know whether the timestamp should be capture at the
top or end of pipeline.

When cloning a chunk of tracepoints, we cannot just copy the elements
of the traces[] array. We also need the payloads associated with
those.
This change introduces a new u_trace_payloaf_buf object that is
refcounted so that we can easily import traces[] elements and their
payloads from one utrace to another.

Re-usable command buffer could be resubmitted any number of times,
but tracepoints are written once. u_trace_clone_append allows
copying tracepoints and copying timestamps if GPU doesn't support
writing timestamps into indirect address.
The case of tiling GPUs is similar, command stream for draws is
resubmitted for each tile.

With little modifications u_trace could be usable for Vulkan drivers.
Beside removing dependencies on gallium, the other notable change is
the passing of opaque flush_data pointer via u_trace_flush. There
is data which becomes available only at this point which other drivers
may want to pass.
For example Vulkan drivers would want to pass at least submission id
(for perfetto) and a sync object to wait on in u_trace_read_ts.
