Add the ability to get per-platform information for joypads.
This adds the ability for games to obtain platform-specific information about joypads such as their vendor/product ID, their XInput gamepad index or the real name of the device before it gets swapped out by the gamecontrollerdb's name.
This PR also includes a rebased version of #76045, this is because this PR is intended to be mainly to help people implementing Steam Input, as having the gamepad index is essential.
