struct method_table_wrapper was introduced to avoid duplicate marking
for method tables.
For example, `module M1; def foo; end; end` make one method table
(mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl.
Classes C1 and C2 includes M1, then two T_ICLASS objects are created
and they points mtbl too. In this case, three objects (one T_MODULE
and two T_ICLASS objects) points same mtbl. On marking phase, these
three objects mark same mtbl. To avoid such duplication, struct
method_table_wrapper was introduced.
However, created two T_ICLASS objects have same or shorter lifetime
than M1 (T_MODULE) object. So that we only need to mark mtbl from M1,
not from T_ICLASS objects. This patch tries marking only from M1.
Note that one `Module#prepend` call creates two T_ICLASS objects.
One for refering to a prepending Module object, same as
`Module#include`. We don't nedd to care this T_ICLASS.
One for moving original mtbl from a prepending class. We need to
mark such mtbl from this T_ICLASS object. To mark the mtbl,
we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended
class `klass`.

This change also introduces the following changes.
* Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
RBasic::flags (2 bit). Age == 3 objects become old objects.
* WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
* LONG_LIVED bitmap to represent living objects while minor GCs
It specifies (1) Old objects and (2) remembered shady objects.
* Introduce rb_objspace_t::marked_objects which counts marked
objects in current marking phase. marking count is needed to
introduce incremental marking.
* rename mark related function and sweep related function to
gc_(marks|sweep)_(start|finish|step|rest|continue).
* rename rgengc_report() to gc_report().
* Add obj_info() function to get cstr of object details.
* Add MEASURE_LINE() macro to measure execution time of specific line.
* and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.

exposing IDs from collectable symbols.
[Bug #10014]
Now, rb_check_id() returns 0 if corresponding symbol is
pinned dynamic symbol.
There is remaining intern_cstr_without_pindown(), it can return
IDs from collectable symbols. We must be careful to use it
(only used in parse.y). I think it should be removed if
it does not have impact for performance.

add:
* STATIC_SYM2ID()
