Add simple implementations of performance.mark/performance.measure --
these aren't fully to spec, and in particular don't have the right base
class or prototype, but they're similar enough for simple use.
Additionally, log trace events for performance.measure, similar to
Chromium -- this allows us to annotate traces collected with d8's
--enable-tracing.

Shell::FetchModuleTree assumes that the module at file_name wasn't
already fetched. Shell::ExecuteModule is calling into
FetchModuleTree without checking if the module is already in the module
map, violating this assumption.
This change fixes this by having Shell::ExecuteModule check for the
existence of the module before calling into Shell::ExecuteModule, the
same way that Shell::DoHostImportModuleDynamically does.

This adds a new API function that can be customized by the embedder
by providing a delegate that defines contexts to be measured and
reports the results to JS.
A memory measurement request is carried out as follows:
1) MeasureMemory(delegate) invocation enqueues a new request in
MemoryMeasurement::received_ and schedules a delayed GC task.
2) At the start of the next GC (that is triggered either by the
GC schedule or by the delayed task) each request in received_
moves to processing_. Per-context marking worklists are created
for each native context that was selected by the delegates
(using the ShouldMeasure predicate).
3) At the end of the GC the sizes of the native contexts are
recorded for each request in processing_. The requests move
to the done_ list and result reporting task is scheduled.
4) When the result reporting task runs it invokes the
MeasurementComplete function of each delegate in done_.
