KDecay 51509a9a3e Change gamepad.rs tuples to normal structs (#4519)
# Objective

- Part of the splitting process of #3692.

## Solution

- Remove / change the tuple structs inside of `gamepad.rs` of `bevy_input` to normal structs.

## Reasons

- It made the `gamepad_connection_system` cleaner.
- It made the `gamepad_input_events.rs` example cleaner (which is probably the most notable change for the user facing API).
- Tuple structs are not descriptive (`.0`, `.1`).
- Using tuple structs for more than 1 field is a bad idea (This means that the `Gamepad` type might be fine as a tuple struct, but I still prefer normal structs over tuple structs).

Feel free to discuss this change as this is more or less just a matter of taste.

## Changelog

### Changed

- The `Gamepad`, `GamepadButton`, `GamepadAxis`, `GamepadEvent` and `GamepadEventRaw` types are now normal structs instead of tuple structs and have a `new()` function.

## Migration Guide

- The `Gamepad`, `GamepadButton`, `GamepadAxis`, `GamepadEvent` and `GamepadEventRaw` types are now normal structs instead of tuple structs and have a `new()` function. To migrate change every instantiation to use the `new()` function instead and use the appropriate field names instead of `.0` and `.1`.
