`unity_native_plugin_entry_point` macro depends on the `unity_native_plugin` crate is imported as `unity_native_plugin`.

[anatawa12]

Currently unity_native_plugin_entry_point macro depends on the unity_native_plugin crate is use-ed as unity_native_plugin.

This is typical case for modern rust since there is extern prelude, however, this may not true in some cases:

• When the macro is reexported in other crate
• When the macro is used inside a macro in another crate B, and used in another crate C.

I think the macro should use $crate instead to access their crate.
