render: GL/GLES now draw lines almost perfectly matching software renderer. 
One place known to differ in a significant way is a single line segment that
starts and ends on the same point; the GL renderers will light up a single
pixel here, whereas the software renderer will not. My current belief is this
is a bug in the software renderer, based on the wording of the docs:

"SDL_RenderDrawLine() draws the line to include both end points."

You can see an example program that triggers that difference in Bug #2006.

As it stands, the GL renderers might _also_ render diagonal lines differently,
as the the Bresenham step might vary between implementations (one does three
pixels and then two, the other does two and then three, etc). But this patch
causes those lines to start and end on the correct pixel, and that's the best
we can do, and all anyone really needs here.

Not closing any bugs with this patch (yet!), but here are several that it
appears to fix. If no other corner cases pop up, we'll call this done.

Reference Bug #2006.
Reference Bug #1626.
Reference Bug #4001.
...and probably others...

cmake: Don't trust the HAVE_IMMINTRIN_H check on Apple targets. 
Otherwise universal builds might try to include an Intel-specific header
on ARM builds, etc.

Fixes #4753.

Cameron Gutman 5dccffd7e4 Allow usage of the new Condition Variable code with Critical Sections 
Vista and later provide the SleepConditionVariableCS() function for this.

Since SDL_syscond_srw.c doesn't require SRW locks anymore, rename it to
SDL_syscond_cv.c which better reflects the implementation of condition
variables rather than the implementation of mutexes.

Fixes #4051.

Misa 4a9947336c `SDL_RenderSetVSync()`: Restrict `vsync` to 0 or 1 
In the future, we might want to support special swap intervals. To
prevent applications from expecting nonzero values of vsync to be the
same as "on", fail with SDL_Unsupported() if the value passed is neither
0 nor 1.

Misa 4549769d7d Add `SDL_RenderSetVSync()` 
Currently, if an application wants to toggle VSync, they'd have to tear
down the renderer and recreate it. This patch fixes that by letting
applications call SDL_RenderSetVSync().

This is the same as the patch in #3673, except it applies to all
renderers (including PSP, even thought it seems that the VSync flag is
disabled for that renderer). Furthermore, the renderer flags also change
as well, which #3673 didn't do. It is also an API instead of using hint
callbacks (which could be potentially dangerous).

Closes #3673.

render: SDL_RenderGeometry should still render when hidden, in most cases.
