rename all HAL functions from mrb_<feature>_hal_<name>() to
mrb_hal_<feature>_<name>() for better grouping and clarity. this makes all
HAL functions immediately identifiable with the mrb_hal_* prefix.
affected gems:
- mruby-task: mrb_task_hal_* -> mrb_hal_task_*
- mruby-io: mrb_io_hal_* -> mrb_hal_io_*
- mruby-socket: mrb_socket_hal_* -> mrb_hal_socket_*
- mruby-dir: mrb_dir_hal_* -> mrb_hal_dir_*

task.c used clock_gettime() directly, breaking portability. added
mrb_task_hal_sleep_us() to hal interface.

removes mrb_tasks_run and mrb_task_mark_all from task_hal.h as these
are core scheduler functions, not HAL interface functions. only
mrb_tick remains as it must be called by HAL timer callbacks.

separates platform-specific timer and interrupt code into hal-posix-task
and hal-win-task gems. mruby-task now uses HAL interface defined in
task_hal.h, making it easier to port to new platforms.
hal-posix-task: uses sigalrm/setitimer for timer, sigprocmask for irq
protection, and SA_RESTART flag to prevent EINTR on system calls.
hal-win-task: uses multimedia timer API and critical_section for irq
protection.
both HALs support multiple mrb_state instances with single shared timer.
auto-detection loads appropriate HAL based on platform.
