Add a cbool to ctypes.nim

[maxpicklez]

Description

The ctypes.nim file does not include a definition for the bool type. Which was added in C99 and confusingly will be redefined in C23 to bool instead of uint8.

@m..@s..@s..@[email protected]@[email protected]@snico@[email protected]:1137:17: error: conflicting types for 'emscripten_set_main_loop'

Expected Output

A working emscripten wasm page or at least continuation of the compilation process.

Known Workarounds

Revert this commit in the emsdk which reverts the type signature back to int.

Additional Information

C23 redefines bool so this may cause a different issue in the future.
