[PATCH RFC 3/3] rust: hid: demo the core abstractions for probe and remove

[Rahul Rameshbabu]

This is a very basic "hello, world!" implementation to illustrate that the
probe and remove callbacks are working as expected. I chose an arbitrary
device I had on hand for populating in the HID device id table.

  [  +0.012968] monitor_control: Probing HID device vendor: 2389 product: 29204 using Rust!
  [  +0.000108] monitor_control: Removing HID device vendor: 2389 product: 29204 using Rust!
