Yukihiro "Matz" Matsumoto b460554d33 vm.c: generalize pre-dispatch argument count check for C methods ...

Replace check_method_noarg() with check_argument_count() that validates
min <= argc <= max using the full aspec stored in mrb_method_t.flags.
This catches ArgumentError earlier at dispatch time, before entering
the C function.

The old check only handled the special case of aspec==0 (NOARG).
The new check extracts REQ, OPT, REST, POST, KEY, and KDICT from
the aspec and validates accordingly. Keyword hash is counted as
a positional arg only when the method doesn't accept keywords.

Remove MRB_METHOD_NOARG_P macro from proc.h (subsumed by aspec check).
Fix 15 incorrect aspec declarations across the codebase that were
exposed by the stricter enforcement.
