runtime: add scavtrace debug flag and remove scavenge info from gctrace Currently, scavenging information is printed if the gctrace debug variable is >0. Scavenging information is also printed naively, for every page scavenged, resulting in a lot of noise when the typical expectation for GC trace is one line per GC. This change adds a new GODEBUG flag called scavtrace which prints scavenge information roughly once per GC cycle and removes any scavenge information from gctrace. The exception is debug.FreeOSMemory, which may force an additional line to be printed. Fixes #32952.
