libcamera: matrix: Add read-only accessor to internal data
Add a data() function to the Matrix class to access the internal data.
This is useful for code that needs to use the matrix contents as a
linear array, as shown by the RkISP1::Ccm::process() function that needs
to copy the matrix data to a local variable. Simplify that function by
using the new accessor.
