fix: port OSR code to new viz compositor codepath (#17538)

* fix: make OSR work with viz compositor

* fix: update OSR patch

* fix: update patch again

* fix: update viz_osr.patch for macOS

* fix: gn check warnings

* chore: no need to change SoftwareOutputDeviceWinProxy

* chore: add check in case we missed something

* fix: consider scale factor when compare size

* fix: make GPU OSR work

* fix: autofill popups with OSR

* chore: use UNIX line ending for osr_video_consumer

* chore: code is already in defined(OS_MACOSX)

* fix: share same OSR implementation on macOS

This should also fix the crash when there is navigation on macOS.

* test: osr window should not crash after navigation

* fix: make osr work on Mac properly

* fix: software osr on windows

* fix: software osr on Linux

* fix: compilation error introduced with rebase

* fix: split local surface id allocation into two

* Update osr_host_display_client_mac.mm

* chore: update copyright year

* fix: update patch
