pw_sys_io_stm32cube: Extend hardware support

Extends support for more hardware by supporting the following:
- Uarts where tx and rx pins are on different ports.
- Peripherals that are UARTs, not USARTs.

Adds the following new config options which default to
PW_SYS_IO_STM32CUBE_GPIO_PORT for backwards compatibility:
- PW_SYS_IO_STM32CUBE_GPIO_TX_PORT
- PW_SYS_IO_STM32CUBE_GPIO_RX_PORT

Adds the following new config option which default to USART:
- PW_SYS_IO_STM32CUBE_USART_PREFIX

For example, this was useful with the following config on an STM32H7:
  PW_SYS_IO_STM32CUBE_GPIO_AF=8
  PW_SYS_IO_STM32CUBE_USART_NUM=5
  PW_SYS_IO_STM32CUBE_GPIO_TX_PORT=C
  PW_SYS_IO_STM32CUBE_GPIO_TX_PIN=12
  PW_SYS_IO_STM32CUBE_GPIO_RX_PORT=D
  PW_SYS_IO_STM32CUBE_GPIO_RX_PIN=2
  PW_SYS_IO_STM32CUBE_USART_PREFIX=UART

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
