Subject: runtime: make debug.FreeOSMemory call runtime.GC()

runtime: make debug.FreeOSMemory call runtime.GC()

Currently freeOSMemory calls gcStart directly, but we really just want
it to behave like runtime.GC() and then perform a scavenge, so make it
call runtime.GC() rather than gcStart.

For #18216.
