InterpolationFilter_neon.cpp: Fix !TARGET_SIMD_X86 compilation

When TARGET_SIMD_X86 is not defined we do not include
InterpolationFilterX86.h, causing us to miss the transitive include of
Rom.h. This causes compilation to fail due to missing definitions of
g_GeoParams and other global arrays.

Fix this by just including Rom.h directly, matching what is already
present in InterpolationFilterX86.h.
