Reduce embolden effect. DO NOT MERGE

Cherry-pick of Iec1c478171e33751be1cddbaae6a8ec30bb6cbab

Certain CJK glyphs become essentially unreadable when emboldened at
sizes used by common apps like News/Weather. Reducing embolden
strength slightly makes these glyphs much more readable without
sacrificing bold/normal weight differentiation.

[MIPS] MatrixProcsTest is changed, because it was failing on jb@Actions tablet.

test_scale_nofilter() call Clamp and Repeat routines that returns buffer with size of count/2, but in test there was memcmp check with size of count.

test_rotation_affine_filter() and test_perspective_filter() are also changed because clamp and repeat routines called from these tests,
returns buffer with size of count*2, but in tests, there was memcmp check with size of count.
