Toolbar: HomeButton without HomepageManager dependency
Made HomeButton work without dependency on chrome.browser.homepage
classes. All the deps are now deferred to ToolbarManager.
The dependencies are injected not through ctor but init method
introduced in this CL since the home button and the enclosing view
(ToolbarLayout) are instantiated from xml.
Menu handling logic was moved to HomepageManager to make it test-
friendly.
Also removed a bunch of dead code in HomeButton. Several public setters
(ActivityTabObserver, ThemeColorProvider, StartSurfaceSupplier) were
used by BrowsingModeBottomToolbarCoordinator only (see
https://crrev.com/c/1981099). There's no callsite left any more as
the class was already gone.
