This commit adds the --longcalls option to UNIQ_CMAKE_ASM_FLAGS for clang
builds of xtensa targets to prevent "dangerous relocation" errors.

0baf2c43cc 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

14e600801e 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.
