Allow to force GC_dump_regularly set on at compilation

* doc/README.macros (GC_DUMP_REGULARLY): Document.
* misc.c (GC_dump_regularly): Turn on by default if GC_DUMP_REGULARLY
macro defined (but not NO_DEBUGGING) - useful for embedded environments.
* misc.c (GC_init): Skip "GC_DUMP_REGULARLY" environments variable check
if GC_dump_regularly already set by the corresponding macro (only if not
NO_DEBUGGING).
