Convert non-flag emoji to COLRv1

File is -6MiB / -68% size and will render more crisply as it is vector
based rather than bitmapped. Ref
https://developer.chrome.com/blog/colrv1-fonts/ for further context.

I believe, and harrytczhang@google.com concurs, the Perf Presubmit is a false positive.

Test: https://github.com/rsheeter/emoji-test-app rendering
Test: presubmit suite, esp CtsGraphicsTestCases, CtsTextTestCases
Test: Skia emojibench (https://docs.google.com/spreadsheets/d/1mexI8Nyj9QigYtyCjUKI3UrYdKbKFqAB1SABWK4yRh0/edit?resourcekey=0-sttMOT2UaNOVTr0qqNogiA#gid=0)
Test: adb install Chrome 98, verify COLRv1 renders from system emoji
Test: rendered emoji string in webview test app to confirm COLRv1 emoji draw
