plugins: make test/example plugins work on windows

Browse Source 
Generate a qemu_plugin_api.lib delay import lib on windows, for
windows qemu plugins to link against.

Implement an example dll load fail hook to link up the API functions
correctly when a plugin is loaded on windows.

Update the build scripts for the test and example plugins to use these
things.
