Switch `emboss_cc_library` to use real Starlark rules.

This change creates the `emboss_library` and `cc_emboss_library`
Starlark rules, which mirror `proto_library` and `cc_proto_library`.

This also fixes issues with `.emb` files that import `.emb` files that
import `.emb` files, where imports-of-imports were not always included
in the compilation.

This also required new command-line arguments to `emboss_front_end`
(`--output-file`) and `emboss_codegen_cpp` (`--input-file` and
`--output-file`).
