Rename SaveUpdateAddressProfileIcon* to AddressBubblesIcon*.

This CL is a part of the work on separating SaveUpdateAddressProfile*
into the "Save" and "Update" parts. High level (not necessarily matching
the CLs) overview of the work to be done:
 * Split `SaveUpdateAddressProfileBubbleControllerImpl` into 3 (or 4)
    parts:
    * `AddressBubbleController` - shows/hides specific bubbles,
      controls the page action icon
    * `SaveAddressBubbleController` - save-relevant methods from
      `SaveUpdateAddressProfileBubbleController`
    * `UpdateAddressBubbleController` - update-relevant methods
    * Maybe `BaseAddressBubbleController` - common methods from
      `SaveUpdateAddressProfileBubbleController`
 * Move the bubble type decision to
   `ChromeAutofillClient::ConfirmSaveAddressProfile`
 * Rename `SaveUpdateAddressProfileIconController` to
   `AutofillAddressIconController`
 * Rename `PageActionIconType::kSaveAutofillAddress` to
   `PageActionIconType::kAutofillAddress`
 * Later (out of scope of this refactoring, but dependent on it): add
   the "Add new address" bubble.
