Preserve a format of RPC command definitions

Currently RPC commands are formatted in a way that it's easy to read
and that test/lint/check-rpc-mappings.py can parse it.

To void breaking test/lint/check-rpc-mappings.py script by running
clang-format, RPC command definitions should be disabled for clang-format.
