These are a handful of errors that pop up in UBSAN, a lot of them
depend on compiler-specific behavior such as zero-sized VLAs being
valid, while others plugged some potential bug prone code such as
nullptr derefs.

Add a 'cond' argument to the _MESA_TRACE_SCOPE(),
_MESA_TRACE_SCOPE_NAME() and _MESA_TRACE_SCOPE_FLOW() macros, fix up
the MESA_TRACE_SCOPE(), MESA_TRACE_SCOPE_FLOW(), MESA_TRACE_FUNC() and
MESA_TRACE_FUNC_FLOW() macros depending on it and add the new
MESA_TRACE_SCOPE_IF(), MESA_TRACE_SCOPE_FLOW_IF(),
MESA_TRACE_FUNC_IF() and MESA_TRACE_FUNC_FLOW_IF() conditional macros.
The trace macros are now based on the conditional ones. Code gen stays
the same for all the current traces though since compilers optimize
out the condition to always taken. See the compiler explorer link.
Conditional CPU scope traces are meant to allow builds with either
Perfetto, Gpuvis or sysprof tracing enabled to filter traces at
run-time.

The intent is to provide an easy way to measure the impact of an
optimization, not by measuring the whole workload completion time
but also by measuring certain chunks of the workload like command
buffers, renderpasses, or even separate draws.
A moderate perf win in a rare case may not translate into statistically
signifacant overall result. An optimization also may hurt perf in some
cases and help in other which is also hard to judge from overall perf.
For best results pin cpu/gpu frequencies and disable gpu suspend.
Exclude all unnecessary tracepoints via TU_GPU_TRACEPOINT.

We only use the acquisition time for calculating latency for perfetto
tracks later, and the acquisition time should ideally be the start of the
perfetto flow.
This has been more or less true with very small error margin for vk wsi,
but the wayland EGL buffer handling is a lot more complicated. Moving the
time check into the flow start will make re-using this code for EGL much
simpler.

You need to re-emit name interning when incremental state is lost, so this
is the right home for the HT of "have we interned this name?". The
emitter function is still on the datasource because it needs the
templating to get the tracecontext type, but now getting the locked
datasource is not really necessary other than being way more ergonomic
than repeating the template parameters.

Perfetto is allowed to choose it's own default clock, and before this we just assumed the presentation times reported by the compositor are the same as perfetto's internal clock, which is not always the case. I got a nasty trace where all the wayland presents were in the wrong location. This fixes that by asking the compositor which clock it uses, then passing that along to perfetto.
A workaround for my compositor was setting use_monotonic_clock=true in the perfetto config, as my compositor (and I suspect most others) use the monotonic clock for presentation timestamps. However, asking the compositor is definitely the most correct solution.
I added a clock param to `MESA_TRACE_TIMESTAMP_{BEGIN,END}`, as it's only use that I could see was in wsi_common_wayland, and in general it seems good to be careful about which clock tracing timestamps come from.

We initially tried to deal with that internally by checking some state

This change adds a flag field to the tracepoint to have that
information there and the flags are passed to the record_ts vfunc.
