[Windows] Improve console handling and execute/create_process.
Always build with the GUI subsystem.
Redirect stdout and stderr output to the parent process console.
Use CreateProcessW for blocking `execute` calls with piped stdout and stderr (prevent console windows for popping up when used with the GUI subsystem build, and have more consistent behavior with `create_process`).
Add `open_console` argument to the `execute` and `create_process` to open a new console window.
Remove `interface/editor/hide_console_window` editor setting.
Remove `Toggle System Console` menu option.
Remove `set_console_visible` and `is_console_visible` functions.
