implement Integer#gcd and Integer#lcm methods in mruby-numeric-ext with full
support for both regular integers and bigints.
key changes:
- add mrb_int_gcd euclidean algorithm for regular integer gcd calculation
- implement int_gcd and int_lcm methods with proper type checking and bigint fallback
- add mrb_bint_gcd, mrb_bint_lcm, mrb_bint_abs functions to bigint api
- register gcd and lcm methods with integer class
- add comprehensive test coverage for both regular and bigint cases

To achieve this, the following changes were made:
- Exported `mrb_bint_size`, `mrb_bint_from_bytes`, and `mrb_bint_sign`
functions from `mruby-bigint` to be used in other mrbgems.
- Modified `mruby-random` to use these new functions to handle Bigint
arguments in the `rand` method.

This commit introduces memory prefetching to the `bsearch_idx` functions
in `src/class.c` and `src/variable.c` to improve performance.
A new macro `MRB_MEM_PREFETCH` is defined in `include/mruby/variable.h`
which uses `__builtin_prefetch` if available.

This commit addresses feedback on the initial Set GC marking implementation.
Changes include:
- Renamed set marking function to `mrb_gc_mark_set` and updated its
return type to `size_t`.
- Introduced an explicit `mrb_gc_free_set` function for Set objects.
- Updated `gc_mark_children` to use the new mark function signature.
- Added an explicit `case MRB_TT_SET:` in `obj_free` to call `mrb_gc_free_set`.
- Adjusted `set_get_khash` in `mruby-set` to work with `MRB_TT_SET` directly,
rather than relying on `mrb_data_get_ptr`.
- Corrected type checks in `set_init_copy` to use `MRB_TT_SET`.
- Updated function prototypes in internal headers and stubs in mrbc.
mempool.h provide compatibility layer so that existing programs does not
need to update (but update recommended anyway, since compatibility layer
takes mrb_state that is not used at all).
There was a problem with visibility state from proc that straddles a fiber or is independent.
Therefore, it has been changed to give priority to env objects, if any.
Also, added "separate module" flag to block traversal to a higher level env object.
Note that the "separate module" flag is now set when calling blocks with the `mrb_yield_with_class()` function.
