Reland [Mac] Created Suggested Text Touch Bar

When text is selected in a textfield, the touch bar displays options
to replace the selected text. Clicking on one of the options will
replace the selected text with the selected option.

Currently, there are no functional unit tests for the suggested text
touch bar. As functionality is fleshed out, unit tests will be
created.

A new folder (chrome/browser/ui/cocoa/touchbar) was created to house all
files related to the Mac touch bar. The
CreditCardAutofillTouchBarController files and the
WebTextfieldTouchBarController files were moved to this new folder.
Dependencies and header guards were updated to reflect this change.

New files:
  - suggested_text_touch_bar_controller.h
  - suggested_text_touch_bar_controller.mm
  - suggested_text_touch_bar_controller_browsertest.mm
Moved files:
  - credit_card_autofill_touch_bar_controller.h
  - credit_card_autofill_touch_bar_controller.mm
  - credit_card_autofill_touch_bar_controller_unittest.mm
  - web_textfield_touch_bar_controller.h
  - web_textfield_touch_bar_controller.mm

BUILD files were updated to accommodate the change in location for the
moved files and to include the new files.

RenderWidgetHostViewMac now informs its RenderWidgetHostDelegate
(WebContentsImpl) when RenderWidgetHostViewMac::OnTextSelectionChanged()
is called. WebContentsImpl then notifies its observers that
the text selection changed.

A feature flag SuggestedTextTouchBar was created and added to
chrome://about so that the new touch bar is disabled by default and
can be enabled via command line or chrome://flags with the flag

This CL includes the following browser tests for
SuggestedTextTouchBarController:
  - SetTextTest
  - TouchBarTest
  - TextSelectionChangedTest

This is a reland of crrev/c/1096443 with the following addition:
A check was added to see if the SuggestedTextTouchBar feature flag
is enabled around the initialization of SuggestedTextTouchBarController
and its WebContentsObserver. This way, the controller and observer are
not initialized unless they are actually going to be used.
