tools: use riscv32-esp-elf toolchain for ESP32-S2 RISC-V ULP

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.
