Clean cache between Apple builds (#12563)

### Summary

In this diff, we clear the CMakeCache.txt between builds since we reuse
the same build output for all the builds. Keeping the cache means that
configuration between each build won't be reflected (i.e.
#12469).

### Test plan
CI

I also tested to ensure that `EXECUTORCH_ENABLE_LOGGING` is being
properly set based on the build mode.

```
-- PLATFORM: OS64
-- CMAKE_BUILD_TYPE: Release
-- EXECUTORCH_ENABLE_LOGGING: OFF
-- ----------------------------------------------------
-- PLATFORM: OS64
-- CMAKE_BUILD_TYPE: Debug
-- EXECUTORCH_ENABLE_LOGGING: ON
-- ----------------------------------------------------
-- PLATFORM: SIMULATORARM64
-- CMAKE_BUILD_TYPE: Release
-- EXECUTORCH_ENABLE_LOGGING: OFF
-- ----------------------------------------------------
-- PLATFORM: SIMULATORARM64
-- CMAKE_BUILD_TYPE: Debug
-- EXECUTORCH_ENABLE_LOGGING: ON
-- ----------------------------------------------------
-- PLATFORM: MAC_ARM64
-- CMAKE_BUILD_TYPE: Release
-- EXECUTORCH_ENABLE_LOGGING: OFF
-- ----------------------------------------------------
-- PLATFORM: MAC_ARM64
-- CMAKE_BUILD_TYPE: Debug
-- EXECUTORCH_ENABLE_LOGGING: ON
-- ----------------------------------------------------
```
