  [mlir][LLVM] Finer-grained control for C interface emission

C interface emission is controlled by a flag and has coarse granularity.
With this coarse control, interfaces are emitted for all external functions.
This makes is easy to get undefined symbols.

This revision adds support for controlling per-function emission with an "emit_c_interface" attribute.
