Fix libusb build fail for golang >= 1.24

[nekoteoj]

Fix for issue #303

Problem:
Go version 1.24 doesn't allow defining a method for non-local structs including created structs with type aliases.

Solution:
The solution is to update the libusb's types from type aliases to type definitions. For example, type Struct_Libusb_Endpoint_Descriptor = C.struct_libusb_endpoint_descriptor is changed to type Struct_Libusb_Endpoint_Descriptor C.struct_libusb_endpoint_descriptor. However, this change prevents the defined types and the C interop types to be used interchangeably without the explicit type casting. As a result, we also needs to explicitly cast the variable types when the go codes interact with c codes. With these changes, I can build the project using go 1.24. It can be built with older go version as well.

I tested this with my Trezor one and it works great. I can use Trezor Suite in the browser and connect the wallet with Metamask.

Please let me know if you have any suggestions/concerns/comments.

Thank you so much!
