Add HAL for SubGhz peripheral for STM32 WL series

Based on the HAL from stm32wl, the peripheral driver has been
modified to fit into embassy, using the embassy APIs, providing
operation of the radio peripheral.

The initial version does not offer any async APIs, but the example
shows how the radio IRQ can be used to perform async TX of the radio.
