fdct4x4_neon: fix compile w/cl

Use an array for constant initialization rather than array syntax which
assumes the underlying type is a vector. Fixes compile error with
cl targeting Windows Arm64:

vpx_dsp\arm\fdct4x4_neon.c(55,52): error C2078: too many initializers

No change in assembly with gcc 12.2.0 & clang 14.
