The window title format and captive portal title strings in
brave_origin_strings.grd were still showing "Brave" instead of
"Brave Origin", and the chrome.dll icon resources (used for the
per-window HICON via WM_SETICON) were hardcoded to the brave/
theme path with no IS_BRAVE_ORIGIN_BRANDED gating. The chrome.exe
icons (brave_exe.rc) were already correctly gated, which is why
shortcut/taskbar icons were correct but alt+tab was not.
- Add IDS_BROWSER_WINDOW_TITLE_FORMAT and
IDS_CAPTIVE_PORTAL_BROWSER_WINDOW_TITLE_FORMAT to
ORIGIN_BRANDED_MESSAGES in chromium-rebase-l10n.py so the
branding rewrite picks them up on every rebase.
- Update the currently-checked-in brave_origin_strings.grd to
apply the same branding now.
- Gate chrome/app/chrome_dll.rc icon resources on
IS_BRAVE_ORIGIN_BRANDED, mirroring brave/app/brave_exe.rc.
- Define IS_BRAVE_ORIGIN_BRANDED for the chrome_dll_resources
source_set when is_brave_origin_branded=true.
