decode: fix NEON inclusion (#714)
The macro that checks for NEON support should be __ARM_NEON, not __ARM_NEON__. [1] AArch64 compilers define __ARM_NEON but not __ARM_NEON__. AArch32 compilers currently seem to define both, but could be within their rights to drop __ARM_NEON__ in future versions. This change moves the check into the common/platform.h file, checks for both forms, and sets BROTLI_TARGET_NEON if NEON support is available. [1] Section 6.5.4 of the ARM C Language Extensions. (At the time of writing, the latest version was Release 2.1.)
