riscv32-esp-elf toolchain (used for ESP32-C3) can also be used for ESP32-S2 RISC-V ULP coprocessor. This removes the riscv-none-embed-gcc toolchain which was originally used for the ULP, and updates the docs and CMake files to use riscv32-esp-elf. Some flags are cleaned up and workarounds removed from CMake toolchain file.
