Windows: Add support to compile python api docs from make file

This adds support to compile the html python api docs from the command line by running `make doc_py` matching support between windows and unix.

This patch also makes it so the compiler is not needed if you set the `blender_bin` variable, this affects icon generation as well.

In the future, I want to move away from generating the build output in the build directory but that can come in a later change.
