Deprecate compiled statement continuations in jdbc (#3659)

The CONTINUATION_CONTAINS_COMPILED_STATEMENT usage was cut down to
always being true in #3650. It was enforced to always be so in release
`4.7.1.0` for JDBC connections which would fail queries explicitly
marking it as false. Now, this PR removes the check and marks the proto
field as deprecated.
