This commit adds support for a scheduler that runs a scheduler on all available cores. It is meant to be used on baremetal systems with a fixed number of cores, such as the RP2040. The initial implementation adds support for multicore scheduling to the riscv-qemu target as a convenient testing target. This means that this new multicore scheduler is tested in CI, including a bunch of standard library tests (`make tinygo-test-baremetal`). This should ensure the new scheduler is reasonably well tested before trying to use it on harder-to-debug targets like the RP2040.
