Split string-sending debugger API into output- and log-sending functions (#2461)

This helps to avoid the use of non-public headers and
protocol-internal constants in external code (e.g., in jerry-port
and jerry-ext).

The patch also cleans up the necessary includes in jerry-core public
headers, and the include order in jerry-port/default public headers.
