BLI_math: add mat3_normalized_to_* functions
...
Many uses of matrices for rotation keep them normalized,
so no need to normalize each time.

BLI_math: add mat3_polar_decompose, interp_m3_m3m3 and interp_m4_m4m4.
...
mat3_polar_decompose gives the right polar decomposition of given matrix,
as a pair (U, P) of matrices.
interp_m3_m3m3 uses that polar decomposition to perform a correct matrix interpolation,
even with non-uniformly scaled ones (where blend_m3_m3m3 would fail).
interp_m4_m4m4 just adds translation interpolation to the _m3 variant.

BLI_matrix space_transform: Add a 'local-invariant' setter.
...
`BLI_space_transform_from_matrices()` defines a 'global-invariant' transform
(same point in global space, two different coordinates in local and target spaces).
New `BLI_space_transform_global_from_matrices()` is kind of opposite, it defines
a 'local-invariant' transform (two different points in global space, same coordinates in local and target spaces).
Useful to 'match' meshes.

Fix T43711: dual quaternion deform bug with shearing in deform matrix.
...
This also increases the tolerances in is_orthogonal / is_orthonormal functions,
which were much too low for practical purposes.

Complementary fix for rB8054372: Follow the common naming scheme by

using negate_mat3_m4 instead of negate_m4.
This avoids changing the behavior and only flips the 3x3 part of the
matrix.

Math Lib: rename mul_serie_m3 to mul_m3_series & reorder args

Importantly, reversed mul_serie_m3 argument order (so it matches the m4 function)

Correction to 7c7b730, multiplication order was flipped
...
That's really annoying that multiplication order is flipped
comparing mat3 and mat4 cases, but for the purposes of not
breaking all the branches which might use this stuff we'd
better keep order consistent with old version for now.
Suggestion here would be to make order consistent but rename
this functions to mult_* to make compilation fail instead
of failing and using wrong order silently.

Bake-API: relaxing in the check for scale uniformity
...
It still warns the user that there may be an error, but the baking goes
on. Also using the new is_uniform_scaled_m4() instead of float comparison.

Fix T38870: Freezes when jumping in front of a keyframe.
...
Issue was caused by inverting a degenerate matrix when
evaluating drivers.
Solved by using tweaked inverse code (same as used in Cycles).
Should have no affect on cases when matrix is not degenerate.
