cmake: Default to PNG_ARM_NEON=off for arm targets
This matches the configure script - unless the user has requested
anything, no hardware optimizations are autoenabled.
Defaulting to "check" is brittle (that configuration is deprecated
and poorly supported) - and for configurations where it would
make sense (where NEON isn't universally enabled in the compiler)
it didn't end up setting ARM_NEON_OPT to 1 in pnglibconf.h anyway.
This fixes default builds with cmake for iOS and Windows on armv7,
where NEON is universally available (but there's no runtime check
implemented) - but actually using NEON on this architecture
requires explicitly opting in to it when configuring, just like
with the configure script.
