(NOTE: This and dependent CLs will be reverted in a few days after
data collection from the field is complete.)
This change introduces a new task queue concept, Voucher. They
are associated with a currently running task tree. Whenever
tasks are posted, the current voucher is inherited and set as
current in the new task.
The voucher exists for as long as there are direct and indirect
tasks running that descend from the task where the voucher was
created.
Vouchers aggregate application-specific attachments, which perform
logic unrelated to Voucher progression. This particular change adds
an attachment that measures time from capture to all encode operations
complete, and places it into the WebRTC.Video.CaptureToSendTimeMs UMA.
An accompanying Chrome change crrev.com/c/4992282 ensures survival of
vouchers across certain Mojo IPC.

This prepares TaskQueueBase sub classes to be able to migrate to
the location and traits-based API. It re-introduces a Location class
into the webrtc namespace, which is meant to be overridden by Chromium.

See go/postdelayedtask-precision-in-webrtc for context of which use
cases are considered "high" or "low". Most use cases are "low" which
is the default, but this CL allows opting in to "high".
Will be used by FrameBuffer2.

As per go/postdelayedtask-precision-in-webrtc we want to reduce the
precision of PostDelayedTask() in order to schedule work on the CPU
more efficiently. In order not to break "high precision" use cases, a
new API is added to allow opting in to high precision.
PostDelayedHighPrecisionTask() has the same precision that
PostDelayedTask() has today, but by changing the interface's
requirements on PostDelayedTask(), adding the high precision version
of it will unblock making the old PostDelayedTask() API lower
precision.
This CL does not update implementations to support low precision so
until those are updated, both PostDelayedTask() and
PostDelayedHighPrecisionTask() have the same precision (=high).
This CL also adds TODOs to make some rtc::Thread-specific versions
of PostTask/PostDelayedTask obsolete, see
https://crbug.com/webrtc/13582 for more info.

This CL adds a dependecy on rtc_base/system:rtc_export to rtc_event but
only when built as part of Chromium (since rtc::Event should not be
used outside of WebRTC).
It also adds other missing RTC_EXPORTS.
