Removes the handling of the flag independent. The flag will be removed in a followup.

The patch changes handling of V8::PersistentBase that are set to Weak:
- The Scavenger ignores the flag independent.
- The Scavenger keeps alive anything that is marked as Active.
- The Scavenger is free to drop weak handles of non-Active object if they 
  are otherwise dead.

Active:
- Any JSObject will always be marked Active.
- Any JSApiObject will be marked Active if it has been modified (=has elements, properties, etc.)

Converts the ast prettyprinter to printing literals from the raw values
rather than internalized on-heap strings. This enables ast printing before
internalizing, and means we can avoid use of the isolate in the interpreter's
off-thread phase.

Also removes --print-builtin-ast and relies on just --print-ast to print
everything.

Finally, converts FunctionLiteral's debug_name function to return a
char[] which is created from the raw name literal where it exists, rather
than relying on the value having been internalized.
