this can result in an alignment hint on arm causing a SIGBUS. casting
the input ptr to anything aside from its type is unnecessary for memcpy
and is contrary to the intent of this function.

fixes the compile with ENABLE_NEON_BUILTIN_MULHI_INT16X8 without relying
on arm_neon.h when using __builtin_neon_vqdmulhq_v; the typedefs are
assumed to resolve to the same underlying type.

(cherry picked from commit 4fbdc9fb12e515aad41adb08692c6bdbf5999bf9)
add a check for cpu-features.h and rework some of the ifdef's around
android + neon. for android builds with cpu-features enabled the
*_neon.c files will still need to be flagged correctly (with e.g.,
.c.neon in Android.mk) to properly build them.

this workarounds an ICE with clang. WASM overrides the native simd so
apart from binary size building it isn't an issue.

WASM needs to precede platform specific architecture checks as the
defines will still be present when building this target.

stub + basic cmake support for targeting native code generation using
portable intrinsics / wasm (WebAssembly). integrating this into the
webp_js path will be left until the implementation is more complete.
