Well, after that accidental STM32F firmware upgrade, I've inserted the
board with the button pressed (it has only one button), it was detected as
serial device, then I've connected to it using terminal, pressed enter and
saw this:

I've uploaded firmware out of the board (pressed 2) and found, that it is
the same as CompositeForSTM32W.bin from the v.2.x.x.x stm32w_flasher.
Then I looked inside the firmware and found the same text. Then I've
taken  CompositeForSTM32W.bin from the previouse (v1.x.x.x) version and
uploaded it into the board.
That's how I've restored it.
BTW, this lines can be found in ST example of the UART IAP bootloader,
except that the sources provided by ST allow firmware upgrade via HW UART,
not USB virtual port, so the next obviouse step is to develop my own
version of the IAP using two examples from ST. Without that weird
"Mouse+COM port" composite device. For the board without any sensors and
only one button. Weird.

Oops, this is interesting. I saw this output in Instant Contiki VM
stm32w_flasher, but it still was unable to flash.

At the point I have 3 versions of the stm32w_flasher:
1. Coming with Contiki 2.5 - crashes silently
2. Out of the Instant Contiki - can flash FTDI, can't flash STM32F based
boards
3. Out of EmberZNet SDK (distributed via ST site) - can flash all boards
with 'old' IAP, boards with new IAP can't be passed to VM.

Also there is a possible way to adopt stm32flasher open source project, but
it also can't be used if the STM32F firmware is... well, proprietary.
A little bit longer way than I thought.
