feat(core): support generics (especially Param) in #[command] (#1622) 
* wip: param argument proof of concept for #[command]

* use macros for automatic type inference in commands

* refactor command for better error handling

* remove redundant ToTokens impl for Wrapper and Handler

* create `StateP` to allow state to use type inference during commands

* wrap State instead of T

* remove accidental edit of attribute

* remove StateP

because we recommend `_: Window<P>` for type inference, the following
function types are now supported:
* Pat::Wild (arg: "_")
* Pat::Struct (arg: final path segment)
* Pat::TupleStruct (arg: final path segment)

* add wildcard, struct, and tuple struct commands to examples

* better unsupported command argument message

* feat(examples): move some commands to a separate module

* add change file

patch

#[command] now generates a macro instead of a function to allow passing through Params and other generics. generate_handler! has been changed to consume the generated #[command] macro
