Replace all int64_t, uint64_t, uint32_t, and int32_t with mrb_int
in the HAL struct, timeval, and function signatures. All values
originate from or end up as mrb_int at the Ruby layer. Also removes
dead overflow checks in callers and the stdint.h dependency from
io_hal.h.

int64_t was unnecessary; readlink(2) returns ssize_t (bounded by
PATH_MAX), and the Windows HAL just raises NotImplementedError.

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_*

separates platform-specific code into hal-posix-io and hal-win-io gems,
making mruby-io platform-independent. HAL interface defined in
mrbgems/mruby-io/include/io_hal.h covers file operations, I/O operations,
and process operations. follows mruby-task dependency pattern where HAL
gems depend on feature gem. ws2_32 library linked in hal-win-io gem.
