Added tracking of memory usage inside of threads. In addition, the max memory usage is kept track of using a high watermark for both the threads and the isolates. Isolate high watermark information is updated when a thread exits the isolate. The isolate high watermark consists of the sum of all thread high watermarks (including the high watermark of the exiting thread). High watermark information for both threads and isolates is now visible in the isolate view in the Observatory.

Added methods to surface number of zone and scoped handles in each isolate. These values are displayed in the isolate view page in the Observatory. These handle counts for the native IO isolate will be surfaced in another CL.

Before, the VM's dart:typed_data was a complete replacement of the SDK's
dart:typed_data implementation instead of a patch. This is unlike all
the other SDK libraries. This difference requires special-casing for
dart:typed_data in tools that handle the SDK libraries (e.g., the
Analyzer's patching support, the GN build).
This change makes dart:typed_data back into a patch to the SDK's
implementation. It reintroduces a distinction between abstract
interface and concrete implementation classes, so there are more
classes.

- [x] Add `ServiceProtocolnfo` class to dart:developer.
- [x] Add `Service` class to dart:developer.
- [x] Add `Service.getInfo` static method to dart:developer.
- [x] Add `Service.controlWebServer` static method to dart:developer.
API:
```dart
/// Information about the service protocol.
class ServiceProtocolInfo {
/// The major version of the protocol.
final int majorVersion;
/// The minor version of the protocol.
final int minorVersion;
/// The Uri to access the service. If the web server is not running, this
/// will be null.
final Uri serverUri;
}
/// Access information about the service protocol and control the web server.
class Service {
/// Get information about the service protocol.
static Future<ServiceProtocolInfo> getInfo();
/// Control the web server that the service protocol is accessed through.
static Future<ServiceProtocolInfo> controlWebServer({bool enable: false});
}
```
... and add a randomly generated authentication token path prefix that must be passed in to access the service protocol.
Old base url:

New base url:
Observatory listening on http://127.0.0.1:54804/<token>/
For example:

Many tools will need to be updated.

- [x] Add three public fields to the "BoundVariable" service type: declarationTokenPos, visibleStartTokenPos, and visibleEndTokenPos. (naming suggestions welcome!)
- [x] Extend LocalVarDescriptors to hold the declaration token position (it already had the scope visibility boundaries).
- [x] Extend ContextScope to hold the declaration token position.
- [x] Add a unit test which verifies this works for local variables, function parameters, and closure captured variables.

- [x] Make `reloadSources` RPC public.
- [x] Add an optional 'pause' parameter to `reloadSources`. When set to true, the isolate will enter the debug pause loop immediately after reloading sources and before resuming execution. This makes it possible for debugger clients to set breakpoints before resuming.
- [x] Add reload_sources_test which tests pausing after reload.
- [x] Fix a bug in `GetVarDescriptors` where a null code object could be used.

- Conditionally remove fields of Code, Function and ICData that are not used in the AOT runtime.
- Don't include RawClosureData.context_scope_ in AOT snapshots.
- Remove parameter names not needed for method resolution.
- Remove parameter types not needed for function type tests.
- Deduplicate parameter name and parameter type lists.
- Shrink and share the initial MegamorphicCache table.
