Yukihiro "Matz" Matsumoto e7cbd8cc28 mruby-task: add gc protection and optimize task operations ...

Implements dual-mechanism GC protection and optimizes task lookup
using pointer arithmetic based on PicoRuby reference implementation.

GC Protection:
- Add mrb_gc_register/unregister to protect Task objects
- Implement mrb_task_mark_all() to mark task contexts during GC
- Store proc reference in mrb_task to prevent premature collection
- Integrate marking into gc.c root_scan_phase

Performance Optimizations:
- Add MRB2TASK macro for O(1) context-to-task conversion
- Optimize Task.current: O(n) queue search -> O(1) pointer arithmetic
- Optimize Task.pass: simplify to root context check
- Optimize Task.join: use MRB2TASK for current task lookup

Bug Fixes:
- Fix MRB_TASK_CREATED/STOPPED to use MRB_FIBER_TERMINATED
- Add safety check to prevent execution of terminated tasks
- Initialize callinfo PC to bytecode start in task_init_context
