Update USBD library to match USBFS API & support HID

[cheyao]

Tested with examples:

• bootloader
• usbfs_bulk_echo
• usbfs_cdc_tty
• usbfs_device
• usbfs_cdc_ecm (Not 100% sure if I'm accessing the network interface correctly, not a networking guy)

Update:

• usbfs_msc now works

Limitations:

• USBD peripheral is fundamentally different from USBFS, so anything that access raw USBFS will take effort to port (usbfs_cdc_uart)

PS. The code style is base on clang-format in this repo. (My usual style isn't this xD)

Also fixed the usbd demo

@biemster @monte-monte can you review this?

[biemster]

i can review when I'm back from holiday.
One thing i can say now is that msc should work, i use that with the current usbd extralib. but that doesn't have to be a blocker for this pr although it is a regression.

[cnlohr]

I will leave this open for you.

@cnlohr I've just updated the lib to fix a few bugs. Now all the examples that don't heavily rely on USBFS work!

Just need a 👍 from @monte-monte and @biemster
