  [libc] Add TIOCGWINSZ and struct winsize support (#203919)

Added support for the TIOCGWINSZ ioctl command.

* Defined struct winsize in llvm-libc-types.
* Defined TIOCGWINSZ in linux/sys-ioctl-macros.h.
* Exposed struct_winsize and TIOCGWINSZ in sys/ioctl.yaml.
* Added struct_winsize proxy header in hdr/types/struct_winsize.h.
* Added a unit test in test/src/sys/ioctl/linux/ioctl_test.cpp.
