HID SharedMem Rework (#1003)

* Delete old HLE.Input

* Add new HLE Input.

git shows Hid.cs as modified because of the same name. It is new.

* Change HID Service

* Change Ryujinx UI to reflect new Input

* Add basic ControllerApplet

* Add DebugPad

Should fix Kirby Star Allies

* Address Ac_K's comments

* Moved all of HLE.Input to Services.Hid
* Separated all structs and enums each to a file
* Removed vars
* Made some naming changes to align with switchbrew
* Added official joycon colors

As an aside, fixed a mistake in touchscreen headers and added checks to
important SharedMem structs at init time.

* Further address Ac_K's comments

* Addressed gdkchan's and some more Ac_K's comments

* Address AcK's review comments

* Address AcK's second review comments

* Replace missed Marshal.SizeOf and address gdkchan's comments
