Dependencies/versions of several crates don't match anymore

[ThyMYthOS]

@Fabien-Chouteau @JeremyGrosser

• cortex_m 0.5.0 depends on hal ~0.3
• usb_embedded 0.3.1 depends on hal ~0.4
• rp2040_hal 2.3.0 depends on cortex_m 0.5.0 and hal ~0.3
• stm32f0x2_hal 0.3.0 depends on cortex_m 0.5.0 and hal ~0.3

So in order to update rp2040_hal and/or stm32f0x2_hal to usb_embedded 0.3.1, cortex_m has to be updated to depend on hal ~0.4.

Hi @ThyMYthOS I forgot to mention that we published 1.0.0 released of hal, cortex_m, usb_embedded, atomic, and bbqueue.

But it looks like you already have the news.
