James Clark ee73fe99f7 perf auxtrace: Allow number of queues to be specified
Currently it's only possible to initialize with the default number of
queues and then use auxtrace_queues__add_event() to grow the array.

But that's problematic if you don't have a real event to pass into that
function yet.

The queues hold a void *priv member to store custom state, and for
Coresight we want to create decoders upfront before receiving data, so
add a new function that allows pre-allocating queues.

One reason to do this is because we might need to store metadata (HW_ID
events) that effects other queues, but never actually receive auxtrace
data on that queue.
