plugins: remove previous n_vcpus functions from API

Browse source 
This information is already accessible using qemu_info_t during plugin
install.

We will introduce another function (qemu_plugin_num_vcpus) which
represent how many cpus were enabled, by tracking new cpu indexes.

It's a breaking change, so we bump API version.
