Ömer Sinan Ağacan affc3392a0 [dart2wasm] Implement Wasm FfiNative support
This CL introduces a new kernel-to-kernel pass in Wasm backend to
compile `FfiNative`-annotated external functions to external functions
with `wasm:import` pragmas.

The new pass `WasmFfiNativeTransformer` extends `FfiNativeTransformer`.
Some `FfiNativeTransformer` methods made public to allow reuse in the
pass.

The conversion works like this: when we see a member like:

    @FfiNative<Int8 Function(Int8, Int8)>("ffi.addInt8")
    external int addInt8(int a, int b);

We generate a Wasm import using Wasm ABI types according to emscripten
calling conventions:

    @pragma('wasm:import', 'ffi.addInt8')
    external static WasmI32 addInt8_$import(WasmI32 a, WasmI32 b);

and convert the original member (`addInt8()`) to a wrapper function that
calls the Wasm import, converting the arguments and return values to
Dart types:

    static int addInt8(int a, int b) {
      return WasmI32.toIntSigned(
        addInt8_$import(
            WasmI32::int8FromInt(a),
            WasmI32::int8FromInt(b),
        ));
    }

Build, test, and CI changes:

- Test runner now uses `// SharedObjects=...` lines in dart2wasm tests
  to pass extra Wasm modules to d8 command used to run the tests.

  Support for `// SharedObjects=...` lines were already used in
  native/AOT FFI tests, not added in this CL. We just start to use those
  lines in dart2wasm tests.

- dart2wasm gn file updated with a target "test_wasm_modules" that
  builds FFI test Wasm modules to Wasm using emcc (emscripten C
  compiler).

- CI dart2wasm_hostasserts configuration updated to copy the Wasm files
  generated by the "test_wasm_modules" target to the shards.
