* include/ruby/ruby.h, gc.c, vm_trace.c: add internal events.
* RUBY_INTERNAL_EVENT_NEWOBJ: object created.
* RUBY_INTERNAL_EVENT_FREE: object freeed.
* RUBY_INTERNAL_EVENT_GC_START: GC started.
And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'.
Internal events can not invoke any Ruby program because the tracing
timing may be critical (under huge restriction).
These events can be hooked only by C-extensions.
We recommend to use rb_potponed_job_register() API to call Ruby
program safely.
This change is mostly written by Aman Gupta (tmm1).

[Feature #8107]
* include/ruby/debug.h, vm_trace.c: added two new APIs.
* rb_tracearg_event_flag() returns rb_event_flag_t of this event.
* rb_tracearg_object() returns created/freeed object.
* ext/-test-/tracepoint/extconf.rb,
ext/-test-/tracepoint/tracepoint.c,
test/-ext-/tracepoint/test_tracepoint.rb: add a test.
