Attribute Macros

• host_fn
  host_fn is used to import a host function from an extern block
• plugin_fn
  plugin_fn is used to define an Extism callable function to export
• shared_fn
  shared_fn is used to define a function that will be exported by a plugin but is not directly callable by an Extism runtime. These functions can be used for runtime linking and mocking host functions for tests. If direct access to Wasm native parameters is needed, then a bare extern "C" fn should be used instead.
