Upgrade TinyUSB

[kilograham]

This will land in 1.4.0 not 1.3.x as there may be minor incompatibilities (if major we should consider 2.x)

At this point we should undo #819

see also #1044

I guess when this does happen, we'll also want to update the USB examples in pico-examples too? (and also update the pico-examples README.md to mention any new USB examples that get added)

merged into develop

bump 😉

In #791 @kilograham pointed to the tinyusb_host_msc_file_explorer example, but that's not mentioned at https://github.com/raspberrypi/pico-examples#usb-host even though it is listed at https://github.com/hathach/tinyusb/tree/master/examples/host . In fact it looks like all the USB host examples there do include mcu:RP2040 in their only.txt files?

well, i didn't re-read all the comments as the title was quite explicit ;-)
