Configure conflicting ARM baremetal cmake flags (#11493)

### Summary

Similar to #11457, but now we
also want to warn against unsupported/conflicting flags. For example,
when using `EXECUTORCH_BUILD_ARM_BAREMETAL`, we cannot enable certain
flags.

### Test plan

CI

```
$ cmake -DEXECUTORCH_BUILD_ARM_BAREMETAL=ON --preset macos

CMake Error at tools/cmake/common/preset.cmake:142 (message):
  Both 'EXECUTORCH_BUILD_ARM_BAREMETAL' and
  'EXECUTORCH_BUILD_EXTENSION_DATA_LOADER' can't be ON
Call Stack (most recent call first):
  tools/cmake/preset/default.cmake:352 (check_conflicting_options_on)
  CMakeLists.txt:87 (include)
```
