Pull in Raspberry Pi's custom RP2350 ARM and RISC-V ports for FreeRTOS. Basic tests run, but stress mutex test is failing in unique and interesting ways. * Add simplified switching test catching task swap problem * Freertosrp2350: use FreeRTOS macros in noInterrupts/interrupts when applicable. (#2456) * Use FreeRTOS macros in noInterrupts/interrupts when applicable. * Fixed calling taskEXIT_CRITICAL and taskENTER_CRITICAL --------- Co-authored-by: fietser28 <fietser28@users.noreply.github.com>
