Use the NDK's cpu-features library when building skia for Chromium/Android.
This patch ensures that when Skia is built for Chromium, it will
always use the Android NDK's cpu-features helper library to detect
NEON at runtime.
This is needed because sandboxed Chromium renderer processes cannot
access /proc, and the probing performed in SkUtilsArm.cpp will never
work. As such, the NEON code paths will never be used even when the
device supports them.
Chromium has special code that ensures that the browser process
passes the CPU features flags to every renderer process, but
Skia needs to use android_getCpuFeatures() to get them.
