Update to new native_assets

[mosuem]

Some changes to:

• the generated files, which should be merged upstream in the generator.
• the rust build steps - the hosted binaries should be updated as well.

Introducing a linker script treeshaking unused symbols, but this will compile on linux only due to CLinker not being available on other platforms at the moment.

As user defines are not yet available, dart-lang/native#39, find and read the pubspec by recursing up from the out directory.
