Build: CMake compiler flags will be set, regardless of the cache status Defining CMake variables from the command-line or from another CMake project, such as `-DCMAKE_C_FLAGS= -DCMAKE_CXX_FLAGS=`, caused a link failure as ESP CMake was unable to set its proper compilation flags. Additional CMake compiler flags can now be provided by another project. * Closes https://github.com/espressif/esp-idf/issues/7507

cmake: allow selection of clang based toolchain This is an experimental feature intended at the moment for ESP-IDF developers only. If IDF_TOOLCHAIN=clang environment variable or CMake variable is set, use toolchain-clang-esp32xx.cmake instead of toolchain-esp32xx.cmake. These changes aren't sufficient to actually build any IDF project with clang; subsequent commits add a few workarounds required to do this. Toolchain files are added for esp32 and esp32s2, which are the targets supported in our llvm-project fork at the moment.
