This change drops the use of `contents_height_side_panel_` in favour of `toolbar_height_side_panel_`. It all changes our interface for `SidePanel` to match the changes in upstream for how `SidePanelType` is passed around. Chromium changes: https://chromium.googlesource.com/chromium/src/+/32daa3e6986fa59dc7adeca3104b17b0a0b63f63 commit 32daa3e6986fa59dc7adeca3104b17b0a0b63f63 Author: Caroline Rising <corising@chromium.org> Date: Wed Apr 29 11:37:34 2026 -0700 [Side panel] Make all side panels use the toolbar height side panel view. This removes usage of the content height side panel view and makes the toolbar height side panel layout according to the current feature's SidePanelType. This also removes all no unnecessary uses of SidePanelType as a param for various side panel accessors. In a followup we will rename the toolbar height side panel.
