To implement this, we reattach the DevToolsUIBindings for the current
DevToolsWindow to the RenderFrameDevToolsAgentHost for the activated
WebContents and reset the main connection in the frontend to reconnect
with and enable the new agents.

The Chromium/Google style guides does not enforce curly braces for
single-line if-statements, but does strongly recommend doing so. Adding
braces will improve code readability, by visually separating code
blocks. This will also prevent issues where accidental additions are
pushed to the "else"-clause instead of in the if-block.
This CL also updates the presubmit `eslint` to run the fix with the
correct configuration. It will now fix all issues it can fix.

This patch simplifies some utility methods by applying the following
changes:
1) `type=text/css` is the implicit default for <style> elements and for
<link rel=stylesheet>. Thus, we should omit it in those cases.
This additionally reduces visual clutter in various places,
including the elements pane when inspecting DevTools using DevTools.
2) Prefer `const` over `let` even in dynamically generated scripts,
matching Google's JS style guide.
3) Simplify `leadZero` by leveraging `String.prototype.padStart`, which
shipped in Chrome 51.

The new compiler caught a lot of pre-existing issues in the codebase.
Sadly, the old compiler version was not smart enough to understand the
new changes. Therefore, the changes have be included in the same CL as
the compiler update.
Most of the changes are related to better handling of prototype and
class inheritance, as well as handling of null/undefined tracking.

During frontend load, there are a couple async points after
DOMContentLoaded before the UI can finish initializing. The first
is waiting for all modules to load. The second is waiting for
preferences to be retrieved.
The event for DevTools extensions was being fired on window
load, but it was possible for the above async work to take too long
and the event listener would not be subscribed in time.
This patch addresses this race condition by caching the event info
inside devtools_compatibility and using a callback instead of relying
on Extensions.ExtensionsServer to be constructed before window load.

This patch adds a new dispatcher function to the devtools embedder
which allows the front_end javascript to call into
InspectorFrontendHost.recordUserMetricsAction() to record a user
metrics action.
The implementation is similar to the recordPerformanceHistogram()
function that we added recently, in that it uses the dynamic version of
the UMA helper. This allows the string name of the action to be provided
directly from the javascript without needing a hard-coded native value.
The change also updates the extract_actions.py script so that the
devtools files can be correctly parsed for new UMA calls. Any new ones
will then be correctly added to the actions.xml file by the script.
This change makes it simple to add new UMA calls into the devtools
frontend code so that we can gather actionable, order based telemetry
for new features.

Accessibility testing revealed that there are tab traps in all of the text editors including read only ones. Once keyboard users tab into the editor, they cannot tab out the editor.
This change adds a shortcut to disable/re-enable tab for indentation, which allows keyboard users continue to use tab to navigate to next UI component.

This change adds 4 new performance histograms for the DevTools using the
prefix 'DevTools.Launch':
- DevTools.Launch.Console
- DevTools.Launch.Elements
- DevTools.Launch.Network
- DevTools.Launch.Sources
These histograms measure the time between the DevTools window being
shown during 'DevToolsWindow::ToggleDevToolsWindow' and a point in each
tool that corresponds to the 'ready' state as seen by a user. These end
points are unique to each tool but are as follows:
- Console: At the end of the ConsolePrompt constructor
- Elements: At the end of _updateMetrics when the styles panel has
been populated for the initially selected node
- Network: After the panel is shown
- Sources: After the NetworkNavigatorView has been loaded
These tools were chosen as they represent the most popular in terms of
usage and will allow us to identify any significant performance impact
in the time taken to launch the DevTools when these panels open by
default.
To see time captured by the histograms in terms of a perf trace for
each tool please take a look at the following screenshots:
https://imgur.com/a/rcAgQ8h
In the traces you can see that the end marker for each load is at the
end of the trace near first meaningful paint, and just as the user
will see the content of the tool render fully.
To accomplish the histograms, a new native function has been added to
the DevTools ui bindings/embedder classes called
'recordPerformanceHistogram'. Along with the plumbing and a new helper
function in the frontend javascript Host.UserMetrics file called
'panelLoaded'
When the frontend javascript loads, it will store the initial panel to
be loaded from the preferences. Once that panel has been created and
the appropriate loaded marker has been hit, the duration of the launch
will be calculated using performance.now(). That duration is then sent
to the native code which will fire the appropriate histogram via the
'UMA_HISTOGRAM_TIMES' macros.
The mechanism is similar to the existing one used for enumerated
histograms and can be expanded to fire additional performance histograms
in the future.
Also added a new test for user-metrics to ensure that the panelLoaded
function will correctly record the histograms.

This reverts commit 82ef33772f758883cda6379610b24f27e7ff3bbe.
Implements this change:
https://github.com/w3c/csswg-drafts/commit/5b5db39d21f3658ae2f4d7992daaf822aca178d8
external/wpt/css/css-flexbox/percentage-heights-003.html ostensibly tests
this, but I don't think the test is correct (and we don't pass it)
To fix the regression from the original change, I updated the devtools code
to specify a flex-basis of auto. It previously defaulted to 0%, which
used to be resolved to auto, but with this change resolves to 0px,
which is not what the code wants.

This patch uses the remoteVersion of the devtools being run to apply
only the fixes that are needed.
Additionally, use of the /deep/ selector is swapped out for injecting
a stylesheet in every shadow root.
