Use floating point math and saturated_cast to calculate the transform.
Refactor CFX_BilinearMatrix::Transform() to share common code, instead
of using integer math and CheckedNumerics.

Currently, all three of CFX_Matrix::TransformRect() take in rect values
and modify them in place.
This CL converts them to take in constant values and return the
transformed values instead, and fixes all the call sites.

The bool returned by Start was not being used and the method was always
called right after the constructor, so it should be in the constructor.

If any of the values in the matrix used to initialize the
CFX_BilinearMatrix are close to INT_MAX then the numbers can overflow
when multipled causing undefined behaviour.
This Cl uses a pdfium::CheckedNumeric to handle the multiplications and
then assigns back to the int value if valid.
