Reland emitting of DataCount section (#2027)

This reverts commit cb2d63586c08a3dd194d2b733ceb3f5051c081f8.
The issues with feature validation were mostly resolved in #1993, and
this PR finishes the job by adding feature flags to wasm-as to avoid
emitting the DataCount section when bulk-memory is not enabled.
