libcamera: matrix: Extend multiplication operator to heterogenous types
It is useful to multiply matrices of heterogneous types, for instance
float and double. Extend the multiplication operator to support this,
avoiding the need to convert one of the matrices. The type of the
returned matrix is selected automatically to avoid loosing precision.
