Mac fixes (#1776)

* macOS build fixes (#1773)

* macOS build fixes

Add missing headers
Threads_Pthreads: do not call pthread_setname_np() on macOS as it does not do
the same as on Linux
DebugStr() -> os_log()

* Make the project build with Makefiles on macOS

* Fix getting modifier key state on Mac (#1774)

We really need to clean up all Carbon calls here (many will go away when the
project switches to SDL2 for all platforms)

* Fix Xcode build; bump minimum version of macOS (#1775)

* Build fixes for the "Unix Makefiles" generator
Pass CMAKE_BUILD_TYPE to the external projects
* Fix indent
