[video_player_web] Add a custom analysis_options file to video_player_web. (flutter#2658)

flutter/plugins is currently red because inline analysis checks are no longer honored.

`video_player_web` used a web-only API that was being flagged (correctly) by the analyzer, but suppressed inline via `// ignore` comments.

Now that `// ignore` comments don't work, the tree has gone red.

A proper fix for `video_player_web` will take longer than acceptable to unblock the flutter/plugins tree. This is a temporary mitigation so work can resume.
