[vm, dart2wasm] Early lowering of FunctionTearOff nodes

FunctionTearOff node represents a tear-off of the 'call' method of
a Function, so it is basically a no-op:

  FunctionTearOff(receiver) == receiver

So we can remove this node early, during lowering transformation on
kernel AST and clean up handling of FunctionTearOff nodes from the VM
and dart2wasm compilation pipelines.

TEST=ci
