Adding new functions to BLI_math_matrix

mult_m4_m3m4_q multiples 4x4 and 3x3 matrices and outputs 4x4 (needed for rotation). It doesn't do safe check!
mul_v4_m4v3 multiples 4x4 matrix by 3d vector and outputs 4d vector
mul_v3_m4v3_q multiples 4x4 matrix by 3d vector and outputs 3d vector. It doesn't do safe check!

rotate_m4_right rotates 4x4 matrix by 90 degrees. Acceptable paxis values are 'X', 'Y', 'Z', -'X', -'Y', -'Z'. Negative char rotatates -90 degrees.
