Apply CI-standard CMake formatting to unblock ci-checks.sh

[Copilot]

This PR addresses the reported CI failure in scripts/ci-checks.sh, where the CMake format check failed on the current branch. The fix is limited to formatting CMakeLists.txt using the same formatter path used in CI.

• CMake formatting alignment

  • Reflowed the file(READ ...) invocation in top-level CMakeLists.txt to match gersemi output.
  • No functional build logic changes; only formatting normalization to satisfy CI.

• Scope

  • Single-file change: CMakeLists.txt
  • No behavior changes to runtime, tests, samples, or schema handling.

# Before
file(
  READ ${CCF_DIR}/doc/host_config_schema/host_config.json
  HOST_CONFIG_SCHEMA
)

# After
file(READ ${CCF_DIR}/doc/host_config_schema/host_config.json HOST_CONFIG_SCHEMA)
