avfilter/vf_removegrain: add x86 and x86_64 SSE2 functions
Speed of all modes increased by a factor between 7.4 and 19.8 largely depending
on whether bytes are unpacked into words. Modes 2, 3, and 4 have been sped-up
by a factor of 43 (thanks quick sort!)
All modes are available on x86_64 but only modes 1, 10, 11, 12, 13, 14, 19, 20,
21, and 22 are available on x86 due to the number of SIMD registers used.
