[vm/concurrency] Move background compiler related state from `Isolate` to `IsolateGroup`

As part of making the compiler independent of `Isolate` we have to move
various state from `Isolate` to `IsolateGroup`. This CL moves background
compiler and related state.

One background compiler will be shared for all isolates within a group.
