The Fuchsia SDK can now be consumed by non-Fuchsia buildroots to produce
Fuchsia artifacts.
The Fuchsia SDK comes with a JSON manifest that describes the various SDK
"parts". GN targets are stamped for each of these parts. The location of these
GN targets can be configured. That location is set to |fuchsia_sdk_root| in
each buildroot. This variable is defined in //build/fuchsia/sdk.gni in each
buildroot. For buildroots that don't care or know about the Fuchsia SDK, that
file may not exist. This is why, the import of that file is guarded behind
the is_fuchsia flag. When the Fuchsia SDK is enabled, that file will define
values for two required variable |using_fuchsia_sdk| and |fuchsia_sdk_root|.
The first flag defines if the SDK is being used. If unset (but defined), the
builds are in-tree. Eventually we want only SDK builds. |fuchsia_sdk_root|
is set to the spot in the buildroot where the GN targets for the SDK parts
are stamped.

Allows categories to be selected through arguments to `trace` instead of changing VM flags and rebuilding.

- Refactoring of the TimelinePage in order to remove the
dependencies from the Service objects.
- Implemented TimelineRepository to abstract the communication layer
- Structured new TimelineDashboardPage with simplified UI and event
filtering
The VM returns lists of events which are forwarded to Catapult.
Some events are white-listed for the common user.
Due to limitations in the way the events are generated the only way to
attach the white-list flag to the events is by adding an extra argument.
By setting the hash of timeline.html to #basic we inform JavaScript that
we require the activation of the filter which forwards just the events
white-listed to Captapult, while preserving all the others during
dumping operations.

This CL routes timeline events to Fuchsia's tracing app when the
following arguments are passed to the VM:
--systrace_timeline
--timeline_recorder=systrace
--timeline_streams=[some streams here]
I'll add these arguments to the Flutter engine for Fuchsia after this
CL lands.

Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.
Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

- Drop no-longer used globally enabled stream flags. This leaves just one source of truth.
- Kill 'Enabled()' for 'enabled()'.
- Store pointer to Timeline::DartStream in Thread.
- Store enabled as an uintptr_t instead of a bool to make it easier for generated code to access.
