Martin Kustermann 5cd42e6b21 [dart2wasm] Start emitting binaryen.inline custom section
Binaryen introduced `binaryen.inline` which allows us to tell it
inlining hints now, including "never inline" hint (see [0])

This allows us to remove the ugly mangling of wasm function names with
`<noInline>` postfix.

We also now pass `--strip-toolchain-annotations`: The annotations
occupy size in the wasm binary and wasm runtimes ignore them (they are
for `wams-opt` only).

Except for IR tests: Here we want to see the annotations, so we keep
them there.

We also rename the package:wasm_builder classes to clearly indicate
those are binaryen specific sections.

We also make the ir_test.dart put it's options first, allowing the IR
tests to override options if needed.
