Changing USB MSC descriptors

[victorallume]

Under Linux, I have a custom MSC-enabled micropython device plugged in, and when I run ls /dev/disk/by-id I get usb-MicroPy_pyboard_Flash_.... Since it's a custom board, I'd like to distinguish it from the pyboard, but I can't find anywhere in the codebase where I can change this identifier. I've tried all of the #defines that seem appropriate (MICROPY_PY_SYS_PLATFORM, MICROPY_HW_USB_MSC_INTERFACE_STRING and a few others), but they make no difference on the MSC side (they do, however, change the VCP descriptors). Is this hard-coded somewhere, or have I not found the right place?

@victorallume this comes from here: https://github.com/micropython/micropython/blob/master/ports/stm32/usbd_msc_interface.c#L102 (which is why it's not easily to grep for).

It would be good to make this configurable via mpconfigboard.h (although awkward that it has to be defined this way as uint8 literals).

I've made a PR for this: #12245

Tried a rebase but still had issues, so I just nuked everything and started a new branch and PR: #12251
