rts: Fix segfault when using non-moving GC with profiling

nonMovingCollect() swaps out the static_flag value used as a sentinel for gct->scavenged_static_objects, but the subsequent call resetStaticObjectForProfiling() sees the old value of static_flag used as the sentinel and segfaults. So we must call resetStaticObjectForProfiling() before calling nonMovingCollect() as otherwise it looks for the incorrect sentinel value

Fixes #25232 (closed) and #23958 (closed)

Also teach the testsuite driver about nonmoving profiling ways and stop disabling metric collection when nonmoving GC is enabled.
