Add SkMatrix44::setColMajord, etc.

We have accessors for efficiently getting the matirx data, and it would be nice
if we had similar methods for setting the matrix entries.

lgtm

Would be nice to add some dox in the header for these (and the getters). Can be
simple, but documenting at least the size of the array parameters would be a
start.

Thanks for the dox.

The next proper stage is to format those so they will line-up with each method
after we run doxygen. We don't do this in a regular way, but we should soon :)
