[ci] Manually roll master

[stuartmorgan-g]

Rolls Flutter master to the version that first failed due to flutter/engine#33688

Updates the camera_windows mocks to include the new method so that the tests will compile on master.

Fixes the blocked roll.

LGTM assuming tests pass

Thanks for working on this! I've been trying all morning to get the windows tests to exclude camera_windows 🤦

Filed flutter/flutter#111484 since this is probably the fourth or fifth time this has come up.

Master failure is flake; I'm going to land this manually so that it runs in parallel with re-running the flake to get the roller going again.
