@digantdesai @zingo @perheld The Arm Zephyr cmake Preset PR was getting too big and including features that weren't directly related to the goal of that PR. I'm splitting into other smaller, more modular PRs to make them easier to review and land. This one is exclusively adding the toolchain option to the |

### Summary This change adds a cmake preset for Arm Zephyr RTOS toolchain. This requires the toolchain cmake compilation target to be added to `PATH` (see #12077 for more details). This change includes update to CI flows, modifying the CI `build_size_test` to run the test using either arm bare metal or Zephyr toolchains. Additionally, the CI for building presets is updated to target the new cmake Zephyr preset. ### Test plan Tested with `test/build_size_test.sh` to determine the correct threshold for running the size test for the arm zephyr toolchain. When the CI runs the size test for the arm zephyr toolchain, the new cmake preset is used directly. The following commands are run by the CI, and can be manually invoked to confirm functionality: ``` CXXFLAGS="-fno-exceptions -fno-rtti -Wall -Werror -Wno-int-in-bool-context -DET_HAVE_PREAD=0" cmake --preset zephyr -DCMAKE_BUILD_TYPE=Release -DEXECUTORCH_OPTIMIZE_SIZE=ON -DCMAKE_INSTALL_PREFIX=cmake-out -Bcmake-out . cmake --build cmake-out -j9 --target install --config Release CXXFLAGS="-fno-exceptions -fno-rtti -Wall -Werror -Wno-int-in-bool-context -DET_HAVE_PREAD=0" cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$(realpath examples/zephyr/arm-x86-64-eabi-gcc.cmake) -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=cmake-out -Bcmake-out/test test cmake --build cmake-out/test -j9 --config Release arm-zephyr-eabi-strip cmake-out/test/size_test ls -la cmake-out/test/size_test ``` Output should corroborate CI test threshold, reporting a resultant `size_test` binary size of ~125Kb (threshold set to 130KB toin CI test tolerate variability). --------- Co-authored-by: ZephyrUser <zephyruser@gmail.com> Co-authored-by: Github Executorch <github_executorch@arm.com>

### Summary Adds the command line option `--target-toolchain` to the `examples/arm/setup.sh` script so that Arm Zephyr toolchain for x86-64 Linux host systems can be used. Sourcing the generated `setup_path.sh` puts the selected toolchain on the `PATH` environment variable. ### Test plan Running: ``` ./examples/arm/setup.sh --i-agree-to-the-contained-eula --target-toolchain zephyr source /home/zephyruser/executorch/examples/arm/ethos-u-scratch/setup_path.sh arm-zephyr-eabi-gcc --version ``` Now produces the following output: ``` arm-zephyr-eabi-gcc (Zephyr SDK 0.17.2) 12.2.0 Copyright (C) 2022 Free Software Foundation, Inc. This is free software; see the source for copying conditions.
