Andreas Kling 74f133293d LibJS: Avoid redundant ExecutionContext allocation for bound functions ...

Instead of creating a second ExecutionContext in BoundFunction.[[Call]],
we now implement BoundFunction::get_stack_frame_size() and combine
information from the target + the bound arguments list.

This allows BoundFunction.[[Call]] to reuse the already-established
ExecutionContext for the callee.

1.20x speedup on MicroBench/bound-call-04-args.js
