This adds a GN target for the 'fuchsia_test' executable and teaches
the GN build about is_fuchsia. Key differences:
*) There's not currently a dart:io implementation for Fuchsia
*) Fuchsia's toolchain currently doesn't support (or need) ldl or lpthread
*) Fuchsia's buildconfig doesn't currently set the is_asan variable

Allow controlling the target ABI by defining TARGET_ABI_IOS or TARGET_ABI_EABI. If neither is defined, default to the previous behavior.
Make Linux, Mac, Android and iOS agree on the value of PreferredCodeAlignment for all architectures.

1. Add "dart_runtime_mode" GN argument. This is an enum with three valid values: "release", "profile", and "develop".
*) "release" builds product precompiled-runtime.
*) "profile" builds non-product precompiled-runtime.
*) "develop" builds non-product non-precompiled-runtime.
2. Remove the redundant "dart_product" GN argument.
3. Kill all *precompiled_runtime static library variants and the related config.
4. Always include the precompiler in gen_snapshot.
5. Support multiple --embedder_entry_points_manifest arguments to gen_snapshot.
6. Update our test harness to use gen_snapshot and pass the same kinds of command line arguments the Flutter folks are using.
7. ASSERT that both DART_PRECOMPILED_RUNTIME and DART_PRECOMPILER are not set at the same time.

This allows the embedder using the gn build files build a VM runtime without compiler-related code, used to run a precompiled snapshot.
It is a copy of libdart, but has the macro DART_PRECOMPILED_RUNTIME defined which excludes all
compiler-related code, not needed to run precompiled code from the binary.
