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.
