wasm-linker: generate 'producers' section

The `producers` section contains meta data of the binary and/or
object file. It *can* contain the source language, the tool it
was processed by, and/or the SDK that was used to produce the file.

For now, we always set the language and processed-by fields to Zig.
In the future we will parse linked object files to detect their
producers sections and append (if different) their language, SDK
and processed-by fields.
