GRAPHICS: Also enable NEON codepath if compiler builds with NEON enabled
...
This will allow to build with NEON on platforms using an old compiler
but with NEON enabled for all translation units.

BACKENDS: ATARI: Remove move16 code
...
There's no evidence of that code being faster than the already optimized
memcpy().

GRAPHICS: ATARI: Utilize dlmalloc
...
- every malloc is now aligned on 16 bytes
- no need for the hidden pointers
- ct60_vmalloc() is called only once, the rest is handled
by dlmalloc (SV XBIOS' vmalloc is pretty fragile)

GRAPHICS: Fix AVX2 path for MultiplyBlend
...
Applies the same fixes to multiply blending in the AVX2
optimized path that were previously applied to the SSE2 path.
Namely, alpha blending and colors now both blend correctly

GRAPHICS: Allow AVX2 optimized blit path to build
...
The way the SIMD blitting paths were previously organized
ensured that the AVX2 one would never actually build. This
commit separates the different implementations into
classes with differing names, ensuring the shadowing
cannot occur.

GRAPHICS: Add SCUMMVM_NEON prepreocessor flag to blit-neon.cpp
...
The blit-neon.cpp file is only added to the project if the flag
SCUMMVM_NEON is defined. However some backends, e.g. iOS, adds the
definition of SCUMMVM_NEON in create_project so the file can be
added to the project during configuration.
The same backend can then unset the definition due to changing
build target, the iOS simulator in this example, which runs can
run on x86_64 hosts which doesn't support NEON.
Since the project still include the source file it will be compiled.
Make sure to not build the file if not SCUMMVM_NEON is defined at
compile time.
