gc.c: extract mrb_obj_alloc_core() for internal allocation

Browse Source 
split mrb_obj_alloc() into type-validation wrapper and allocation
core (mrb_obj_alloc_core). internal callers (mrb_proc_new,
mrb_env_new) use the core directly, skipping 15+ lines of type
validation per allocation.

most impactful for workloads with heavy Proc/Env allocation
(lambda calculus, block-intensive code).
