[Home] Add state change reason to BottomSheet#setSheetState

This change introduces the concept of 'state change reason' to the
bottom sheet. Once setSheetState is called with a reason, that
reason persists through all the events until the sheet reaches its
final state or setSheetState is called again. This change allows
users of the API to make more nuanced decisions based on what
caused the bottom sheet to, for example, open.

The first change to use this API is the placeholder content in the
content controller. If the sheet is opened because of the omnibox
focusing, the placeholder will be shown instead of suggestions.
Previously this was done by immediately replacing the suggestions
content when the omnibox gained focus.

[Home] Refactor sheet open logging to use StateChangeReason

This change removes the explicit logging for the bottom sheet open
reason in favor of the reason that can now be provided. The close
reason will be converted in a separate change.

[Home] Add StateChangeReason as param to BottomSheetObserver.onSheetClosed

This change adds a parameter to onSheetClosed that allows users of the
method to know the reason the sheet was closed. A result of this is
the ability to remove some of the infrastructure around the bottom
sheet's metrics; the reason no longer needs to be explicitly set.
