1. Switch to 8 bit precision.
2. Fix an error in the implementation of MMI and MSA.
About the error:
MMI and MSA implementation for RGBtoY and RGBToYJ used different
precision according to the C implementation( The C version has been
unified in commit fce0fed542001577e6b10f4cf859e0fa1774974e). This
patch unifies the precision to 8 bit for RGBToYJ in MMI and MSA.

The original src_u calculation of FOURCC_I420 shifted half width if
crop_y is odd.
This CL fixs the problem and also add a test case for it.

When loading or storing the data, the unaligned address will greatly degrade
the optimization performance, so non-aligned access instructions are required
on the loongson platform.
Also delete the optimization function:ScaleARGBFilterCols_MMI,
because it degraded the performance.

Currently, libyuv supports MIPS SIMD Arch(MSA),
but libyuv does not supports MultiMedia Instruction(MMI)(such as loongson3a platform).
In order to improve performance of libyuv on loongson3a platform,
this provides optimize 98 functions with mmi.
