GN: turn on easy libjpeg-turbo SIMD backends (ARMv7 and ARMv8)

Browse Source 
These are so easy we might as well...

I did a quick check of relevant-looking defines:
   - GYP defined WITH_SIMD, but it looks like that's already defined (by jconfig.h?);
   - GYP defined RGBX_FILLER_0XFF, but that affects only x86/x86-64;
   - GYP defined STRICT_MEMORY_ACCESS, which does nothing;
   - GYP defined MOTION_JPEG_SUPPORTED, which does nothing (and we'd probably not care anyway).
