Make sure all GraphicsBitmap scanlines are 16-byte aligned.
...
This is a prerequisite for some optimizations.

Kernel: Don't use MMX memcpy() in the kernel.
...
I just discovered the hard way that clobbering FPU/MMX/SSE registers in the
kernel makes things very confusing for userspace (and other kernel threads.)
Let's banish all of those things from the kernel to keep things simple.

Get rid of SERENITY macro since the compiler already defines __serenity__
...
This makes it a bit easier to use AK templates out-of-tree.

WindowServer: Factor out window frame logic into a WSWindowFrame class.
...
The window frame is an object that contains a window, its title bar and
window border. This way WSWindowManager doesn't have to know about all the
different types of window borders, titlebar rects, etc.

AK: Add Retained<T>, like RetainPtr, but never null.
...
Also use some Clang attribute wizardry to get a warning for use-after-move.

Use modern C++ attributes instead of __attribute__ voodoo.
...
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.

Add a fast memcpy() using MMX when we're moving >= 1KB.
...
This is a nice speedup for WindowServer. I'll eventually have to do this
with SSE but the kernel doesn't support SSE yet so this is it for now.

Optimize the Painter::blit() loop a bit. ~3% fewer cycles, I'll take it.
