Separate USB gamepad16 report and descriptor

Fixes #3262

BTStack redefines many USB HID definitions, so need to be careful to not include
full tusb.h before btstack.h.  Keyboard and Mouse didn't need special report
structs, but Joystick (joystick16) did, so it was including TUSB and BTstack
and barfing.

Separate the joystick report struct definition from the HID descriptor
to avoid the issue.
