cogl/trace: Add scoped trace anchors
A trace "anchor" is a trace head (CoglTraceHead) that is placed in a
certain scope (e.g. function scope), but then only triggered in another
scope, e.g. a condition.
This makes it possible to have optional trace instrumentation, that is
enabled only given e.g. a debug flag.
