This method will be used for a test with multiple code spaces, to
encode large function indexes. The current implementation in
{wasmI32Const} just always uses 5 bytes for encoding the LEB value.
This CL adds a {wasmSignedLeb} function which properly encodes the
value, and adds tests for that.
Drive-by: Clean up the rest of {test-wasm-module-builder.js}.

We noticed that almost every call site were loading both files,
the split isn't necessary anymore.
In some message tests, removed the absolute line number to allow future
changes.
