Fix T83351: Baked object rotation has discontinuities

Fix Euler discontinuities in the Bake Action operator, by explicitly
using the previous Euler angles when converting from matrix to rotation.

This basically follows the same approach as used in e4ca1fc4ea43, although
the Euler Discontinuity Filter also performs single-channel filtering which
the Bake Action operator doesn't.
