We were exporting all symbols to the dynamic table so that they could be looked up using `dladdr` for the profiler and backtracer. The symbols include our statically-linked libcxx, which can create trouble when another DSO has a different version of libcxx. Now we export only the VM embedding API functions (`Dart_*`) and use a specially produced table to do the symbolization.

The purpose of the wasm_js_compatibility target is to facilitate experiments with a JS compatibility mode for Dart2Wasm. Initially, we're just going to focus on typed data, but this will give us a place to experiment with moving List and String to JS as well.
In addition, someday down the road we hope to experiment with two additional compatibility changes:
1) Exclusively using double for all Dart numbers
2) Allowing undefined to flow as null.
The two major benefits of this approach are:
1) Much faster JS interop
2) To make it easier to bring up Dart2JS applications on Dart2Wasm
The only downside will be access overhead on the Wasm side, but the JS builtins proposal could potentially bring us close to parity with Wasm builtins someday.
Tested: Wasm specific trivial refactor.

This adds basic infrastructure for a stringref implementation in
dart2wasm:
- A `--[no-]stringref` option to the compiler
- An option in the `WasmTarget`, controlling the name of the target
- Separate sets of patch files for the two targets
- Separate platform dill files for the two targets
For now, the patch file contents are the same, and the compiler flag
is not used by the backend (only by the `dart2wasm` script to select
the appropriate platform dill file). Both of these will change as the
implementation progresses.
Tested: ci + manual check that the option selects the correct dill

The bulid rules generate an appjit snapshot or a kernel file under
dartdev.dart.snapshot depending on whether the target_cpu is the same as
the host_cpu.
Generation of the additional dartdev.dill file is not needed because of
this, the logic to start the dartdev isolate tries to load
dartdev.dart.snapshot as an appjit snapshot first and if that fails it
tries it as a kernel file.
