Alper Nebi Yasak 8b0255991e meson: Set WEBRTC_HAS_NEON macro after handling neon build option ...

The WEBRTC_HAS_NEON macro that enables using NEON implementations is
unconditionally set for arm64 and the 'neon' build option is ignored,
assuming we always want to use the NEON-specific implementations instead
of generic ones. This is an OK assumption to make because arm64 CPUs
always support NEON.

But the code handling the build option ended up quite convoluted. As
part of cleaning up, set the relevant cflags after we handle the build
option. This also means that we can make 'runtime' fall back to 'no',
and disable NEON-specific code with -Dneon=no.
