usb: gadget: Increase max configuration interface to 32

Currently, max configuration interfaces are limited to 16, which fails
for compositions containing 10 UVC configurations with interrupt ep
disabled along with other configurations , and we see bind failures
while allocating interface ID in uvc bind.

Increase max configuration interface to 32 to support any large
compositions limited to same size as usb device endpoints as
interfaces cannot be more than endpoints.
