roll: pigweed, pw_toolchain: pw_uart_mcuxpresso: Introduce DMA UART backend for NXP devices

Add a pw::uart implementation for devices using the NXP Mcuxpresso SDK.

Based on the DMA-backed implementation from pw::stream, in favor of this
API. The implementation has been refactored, adding timeout cancellation
and ConservativeReadLimit support.
