Derive Ord for GamepadButtonType. (#11791)

Browse source 
# Objective

Use `GamepadButtonType` with library that requires `Ord`.

## Motivation

`KeyCode` derives `Ord` that I'm using with a trie for recognizing
[input
sequences](https://github.com/shanecelis/bevy-input-sequence/tree/trie).
I would like to do the same for `GamepadButtonType` but am stymied by it
not deriving `Ord`.

## Solution

This PR add derivations PartialOrd and Ord for `GamepadButtonType`.

## Workaround

If deriving `Ord` is not possible, I'd be happy to know how I might
coerce `GamepadButtonType` into a `u32` or something else that is `Ord`,
so I can wrap `GamepadButtonType` in a newtype. I suppose serializing
with serde may work or reflect?
